O-11 is an analog of the fully saturated, 14-carbon fatty acid myristic acid, in which the methylene group at position 11 is replaced with oxygen. It is highly effective and selective at killingTrypanosoma brucei, the protozoan parasite responsible for African sleeping sickness, exhibiting an LD50of less than 1 μM in a cell culture assay.1,2The toxic effects of O-11 appear to be caused by its ability to inhibit the incorporation of a single myristate into the GPI anchor of the variant surface glycoprotein (VSG), a protein critical for evading the host immune response.1O-11 exhibits essentially no anti-fungal activity when assayed usingC. neoformans, but does have a minor inhibitory effect on HIV-1 replication in T-lymphocytes.3 1.Doering, T.L., Raper, J., Buxbaum, L.U., et al.An analog of myristic acid with selective toxicity for African trypanosomesScience2521851-1854(1991) 2.Doering, T.L., Lu, T., Werbovetz, K.A., et al.Toxicity of myristic acid analogs toward African trypanosomesProceedings of the National Academy of Sciences of the United States of America919735-9739(1994) 3.Langner, C.A., Lodge, J.K., Travis, S.J., et al.4-Oxatetradecanoic acid is fungicidal for Cryptococcus neoformans and inhibits replication of human immunodeficiency virus IThe Journal of Biological Chemisty267(24)17159-17169(1992) | |||

Purfalcamine is an orally active, selective Plasmodium falciparum calcium-dependent protein kinase 1 (PfCDPK1) inhibitor with an IC50 of 17 nM and an EC50 of 230 nM. Purfalcamine has antimalarial activity and causes malaria parasites developmental arrest at the schizont stage[1][2]. Purfalcamine has low activity against Toxoplasma gondii calcium-dependent protein kinase 3 (TgCDPK3)[1]. Purfalcamine (225, 450 nM) has no effect on the parasitemia in the first 32 hours. After about 40 hours, parasite level remains stable and then begins dropping[1]. Purfalcamine inhibits proliferation with EC50s of 171-259 nM for P. falciparum strains (3D7, Dd2, FCB, HB3 and W2), which indicates effectiveness against drug-resistant parasites[1]. Given that the EC50 value for P. falciparum (3D7) is 230 nM, Purfalcamine shows a therapeutic window ranging from 23-fold to 36-fold (EC50s for CHO=12.33 μM, HEp2=7.235 μM, HeLa=7.029 μM and Huh7=5.476 μM)[1]. Purfalcamine (10 mg/kg; oral gavage; BID; for 6 days) demonstrates a delay in the onset of parasitemia in treated mice[1]. Purfalcamine (20 mg/kg; orally gavage) exhibits a Cmax of 2.6 μM with a half-life of 3.1 hours[1]. Animal Model: Male BALB/c mice, 7 weeks of age with the malaria parasite[1] [1].

TMPY-04180 | PfLDH Protein, P. falciparum, Recombinant (His) | P. falciparum | E. coli | ||
Plasmodium falciparum lactate dehydrogenase (PfLDH) is a key enzyme for energy generation of malarial parasites and is considered to be a potential antimalarial target. The ability of PfLDH- or PfIDEh-based immuno-PCR assays to detect <1 parasite/microL suggests that improvements of bound antibody sensor technology may greatly increase the sensitivity of malaria rapid diagnostic tests. The PfLDH test could be used to detect failures and, therefore, to assess anti-malarial efficacy.

TMPH-03143 | PFD0110w Protein, Plasmodium falciparum, Recombinant | Plasmodium falciparum | E. coli | ||
During the asexual blood stage, binds to a sialic acid containing receptor on the surface of the host erythrocyte and thus is involved in merozoite invasion. Binds erythrocytes via a neuraminidase sensitive and trypsin-, chymotrypsin-resistant receptor. After merozoite attachment and reorientation, RH1 binding to its erythrocyte receptor triggers an increase in intracellular Ca(2+) within the parasite resulting in the release of microneme proteins such as EBA175 which in turn leads to the formation of the tight junction between parasite and host cell.

TMPY-02171 | Cathepsin L Protein, Mouse, Recombinant (His) | Mouse | HEK293 | ||
Cathepsin L is a lysosomal cysteine protease that plays a major role in intracellular protein catabolism, and is potent in degrading collagen, laminin, elastin, as well as alpha-1 protease inhibitor and other structural proteins of basement membranes. It is secreted by liver flukes at all stages of their development in the mammalian host, are believed to play important roles in facilitating parasite migration (tissue degradation), feeding and immuno-evasion. Like many proteases, Cathepsin L is synthesized as an inactive preproenzyme, and cleavage of the 96-residue proregion is necessary to generate the fully active 221-residue mature enzyme. Studies have demonstrated that cleavage of the proregion occur autocatalytically under acidic conditions. The enzyme takes part in nutrient acquisition by catabolizing host proteins to absorbable peptides, facilitates the migration of the parasite through the host intestine and liver by cleaving interstitial matrix proteins such as fibronectin, laminin and native collagen and is implicated in the inactivation of host immune defenses by cleaving immunoglobulins. Recently, Cathepsin L has been shown to suppress Th1 immune response in infected laboratory animals making them susceptible to concurrent bacterial infections. Cathepsin L is synthesized in large amounts and secreted by many malignantly transformed cells, and induced by growth factors and tumor promoters. In addition to its role in protein degradation, evidence has accumulated for the participation of Cathepsin L in various physiological and pathological processes, such as tumor invasion and metastasis, bone resorption, spermatogenesis, and arthritis. Accordingly, Cathepsin L may prove useful as a diagnostic or prognostic marker of human tumor malignancy.

TMPJ-01217 | Mgl2 Protein, Mouse, Recombinant (His) | Mouse | Human Cells | ||
Macrophage galactose N-acetyl-galactosamine-specific lectin 2(Mgl2), also known as CD301b, is a 38 kDa member that belongs to the C-type lectin family. Two MGL proteins are encoded by separate genes in the mouse, but share 91% amino acid (aa) identity in the extracellular domain (ECD). Only one MGL occurs in human and rat and this MGL is structurally more similar to mouse MGL1 than MGL2. However, human MGL and mouse MGL2 both bind specifically to terminal GalNAc residues, in contrast with mouse MGL1 which binds Lewis X. GalNAc recognition is likely to be important in dendritic cell-mediated tolerance to self-gangliosides as well as recognition of tumor antigens and parasite glycoproteins.

TMPH-00338 | PRA1 Protein, Candida albicans, Recombinant (His) | Candida albicans | Yeast | ||
Cell surface protein involved in the host-parasite interaction during candidal infection. With MP65, represents a major component of the biofilm matrix. Sequesters zinc from host tissue and mediates leukocyte adhesion and migration. As a surface protein, binds the two human complement regulators CFH and CFHR1, as well as plasminogen PLG, mediates complement evasion and extra-cellular matrix interaction and/or degradation. As a released protein, enhances complement control in direct vicinity of the yeast and thus generates an additional protective layer which controls host complement attack, assisting the fungus in escaping host surveillance. Binds to host fluid-phase C3 and blocks cleavage of C3 to C3a and C3b, leading to inhibition of complement activation. Mediates also human complement control and complement evasion through binding to C4BPA, another human complement inhibitor, as well as through binding to host integrin alpha-M/beta-2. Decreases complement-mediated adhesion, as well as uptake of C.albicans by human macrophages.

TMPY-01771 | Latexin Protein, Mouse, Recombinant (His) | Mouse | E. coli | ||
Latexin, also known as endogenous carboxypeptidase inhibitor, tissue carboxypeptidase inhibitor, TCI, ECI, and LXN, is a cytoplasm protein that belongs to the protease inhibitor I47 (latexin) family. It is highly expressed in the heart, prostate, ovary, kidney, pancreas, and colon. Latexin / LXN is the only known endogenous specific inhibitor of zinc-dependent metallocarboxypeptidases (MCPs) present in mammalians so far. Latexin is originally identified as a molecular marker for the regional specification of the neocortex in development in rats. The 222 amino acid latexin in the human shows different expression distribution with high levels in heart, prostate, ovary, kidney, pancreas, and colon, but only moderate or low levels in other tissues including the brain. Latexin is also expressed at high levels and is inducible in macrophages in concert with other protease inhibitors and potential protease targets, and thus is suggested to play a role in inflammation and innate immunity pathways. Despite the non-detectable sequence similarity with plant and parasite inhibitors, Latexin is related to a human putative tumor suppressor protein, TIG1. Also, Latexin is implicated in Alzheimer's disease.

Kit ligand, also known as Hematopoietic growth factor KL, Mast cell growth factor, Steel factor, Stem cell factor, c-Kit ligand, Kitlg and KITL, is a single-pass type I membrane protein that belongs to the SCF family. KITL / kit ligand also belongs to the family of dimeric transmembrane growth factors. The soluble form of KIT ligand is a secreted protein. Mast cells are thought to participate in a variety of immune responses, such as parasite resistance and the allergic reaction. Mast cell development depends on stem cell factor (Kit ligand) and its receptor, c-Kit. KITL / kit ligand stimulates the proliferation of mast cells. KITL / kit ligand is able to augment the proliferation of both myeloid and lymphoid hematopoietic progenitors in bone marrow culture. Efficient cell surface presentation of KITL / kit ligand is essential for the migration, proliferation, and survival of melanocytes, germ cells, hemopoietic stem cells, and mastocytes. KITL / kit ligand acts synergistically with other cytokines, probably interleukins. KITL / kit ligand plays a crucial role in the development and maintenance of the melanocyte lineage in adult skin. It exerts permanent survival, proliferation and migration functions in Kit receptor-expressing melanocytes. KITL / kit ligand misexpression in some hyperpigmented lesions may open the avenue for Kitl-dependent treatment of pathological skin conditions.

TMPY-01027 | Mast Cell Protease-1/MCPT-1 Protein, Mouse, Recombinant (His) | Mouse | HEK293 | ||
Mast Cell Protease 1 (MMCP-1), also known as MCP-1, MCPT-1 and β-chymase, is a member of the Chymase family of chymotrypsin-like serine proteases. MCPT-1 is a 26 kDa β-chymase that is a component of mast cell granules. It is a 226 amino acid (aa) protein that has a conserved pattern of six cysteines and one potential glycosylation site. The granule-derived mouse mast cell proteases-1 and -2 (mMCP-1 and -2) colocalize in similar quantities in mucosal mast cells but micrograms of mMCP-1 compared with nanograms of mMCP-2 are detected in peripheral blood during intestinal nematode infection. mMCP-1 isolated from serum is complexed with serpins and both the accumulation and the longevity of mMCP-1 in the blood is due to complex formation, protecting it from a pathway that rapidly clears mMCP-2, which is unable to form complexes with serpins. The mucosal mast cell (MMC) granule-specific beta-chymase, mouse mast cell protease-1 (mMCP-1), is released systemically into the bloodstream early in nematode infection before parasite-specific IgE responses develop and TGF-beta1 induces the constitutive release of mMCP-1 by homologs of MMC in vitro. Expression of mMCP-1 is largely restricted to intraepithelial MMC and is thought to play a role in the regulation of epithelial permeability. Its activation is completed by the removal of a two residue N-terminal propeptide by a dipeptidyl peptidase (Cathepsin C). MCPT-1 is upregulated in the intestine in response to nematode infection, or systemic mucosa in response to anaphylaxis. Like human α-chymase, MCPT-1 is capable of the conversion of angiotensin I to angiotensin II, which plays a key role in the regulation of arterial pressure. The intestinal inflammation associated with gastrointestinal helminths is partly mediated by mMCP-1.

TMPH-01073 | CD81 Protein, Human, Recombinant (His & SUMO) | Human | E. coli | ||
Structural component of specialized membrane microdomains known as tetraspanin-enriched microdomains (TERMs), which act as platforms for receptor clustering and signaling. Essential for trafficking and compartmentalization of CD19 receptor on the surface of activated B cells. Upon initial encounter with microbial pathogens, enables the assembly of CD19-CR2/CD21 and B cell receptor (BCR) complexes at signaling TERMs, lowering the threshold dose of antigen required to trigger B cell clonal expansion and antibody production. In T cells, facilitates the localization of CD247/CD3 zeta at antigen-induced synapses with B cells, providing for costimulation and polarization toward T helper type 2 phenotype. Present in MHC class II compartments, may also play a role in antigen presentation. Can act both as positive and negative regulator of homotypic or heterotypic cell-cell fusion processes. Positively regulates sperm-egg fusion and may be involved in acrosome reaction. In myoblasts, associates with CD9 and PTGFRN and inhibits myotube fusion during muscle regeneration. In macrophages, associates with CD9 and beta-1 and beta-2 integrins, and prevents macrophage fusion into multinucleated giant cells specialized in ingesting complement-opsonized large particles. Also prevents the fusion of mononuclear cell progenitors into osteoclasts in charge of bone resorption. May regulate the compartmentalization of enzymatic activities. In T cells, defines the subcellular localization of dNTPase SAMHD1 and permits its degradation by the proteasome, thereby controlling intracellular dNTP levels. Also involved in cell adhesion and motility. Positively regulates integrin-mediated adhesion of macrophages, particularly relevant for the inflammatory response in the lung.; (Microbial infection) Acts as a receptor for hepatitis C virus (HCV) in hepatocytes. Association with CLDN1 and the CLDN1-CD81 receptor complex is essential for HCV entry into host cell.; (Microbial infection) Involved in SAMHD1-dependent restriction of HIV-1 replication. May support early replication of both R5- and X4-tropic HIV-1 viruses in T cells, likely via proteasome-dependent degradation of SAMHD1.; (Microbial infection) Specifically required for Plasmodium falciparum infectivity of hepatocytes, controlling sporozoite entry into hepatocytes via the parasitophorous vacuole and subsequent parasite differentiation to exoerythrocytic forms.
