Ambrein is a triterpene alcohol that is the chief constituent of ambergris, a secretion from the digestive system of the sperm whale, and has been suggested as the possible active component producing the supposed aphrodisiac effects of ambergris. It serves as the biological precursor for a number of aromatic derivatives such as ambroxan and is thought to possess fixative properties for other odorants. It has been shown to act as an analgesic and it has been proven to increase sexual behavior in rats, providing some support for its traditional aphrodisiac use. Ambrein has also been shown to decrease spontaneous contractions of smooth muscles in rats, guinea pigs, and rabbits. It is able to reduce these contractions by serving as an antagonist and interfering with the Ca2+ ions from outside of the cell. |

Lornoxicam-d4 is intended for use as an internal standard for the quantification of lornoxicam by GC- or LC-MS. Lornoxicam is a COX inhibitor and non-steroidal anti-inflammatory drug (NSAID) with anti-inflammatory and analgesic properties. It inhibits production of thromboxane B2 from arachidonic acid in HEL human erythroleukemic cells, which endogenously express COX-1, as well as inhibits LPS-induced formation of prostaglandin F1α from arachidonic acid in Mono-Mac-6 cells, which endogenously express COX-2. Lornoxicam reduces LPS-induced production of nitric oxide and IL-6 in cell-based assays with IC50 values of 65 and 54 µM, respectively. It reduces carrageenan-induced paw edema in rats when administered intravenously at doses ranging from 0.1 to 9 mg/kg. Formulations containing lornoxicam have been used in the management of postoperative pain. |

UFP101是一种合成肽类物质,作为nociceptin受体的拮抗剂(Ki为0.06 nM,测试于表达人类受体的CHO细胞中)。它对nociceptin受体的选择性高于κ-opioid受体(Ki为204 nM,测试于表达大鼠受体的CHO细胞中)。UFP101能抑制表达于CHO细胞膜的nociceptin受体释放GTPγS(EC50为1.86 nM)。通过脑室内给药,UFP101(10 nmol/每只动物)能延长小鼠尾巴甩动试验中的尾巴撤回潜伏期。在由盲肠结扎和穿刺诱发的小鼠败血症模型中,UFP101(0.003、0.03及0.3 mg/kg)能提高生存率。 |
