17(R)-Protectin D1 is an aspirin-triggered epimer of the specialized pro-resolving mediator protectin D1 .1It decreases leukotriene B4-induced transendothelial migration of human polymorphonuclear (PMN) neutrophils when used at concentrations ranging from 0.1 to 10 nM. 17(R)-Protectin D1 (0.01-10 ng) reduces the recruitment of neutrophils in a mouse model of TNF-α-induced peritonitis.

(R)-Butaprost (free acid) 是PGE2的一个结构类似物,特异性地对EP2受体亚型有选择性。该化合物用于药理学研究,以确定不同人类及动物组织和细胞中EP受体的分布。去除甲酯基团并恢复C-1自然羧酸后,增强了(R)-butaprost与前列腺素受体的结合亲和力,通常情况下,游离酸形式的亲和力是相应酯形式的10到100倍。尽管(R)-butaprost作为C-16的较低活性差向异构体,其药理作用未经充分研究,但在1986年Gardiner的论文中提到的TR 4979即布他前列素,结构中的差向异构体错误表达为16(R),实际为16(S),该错误直至1990年代后期才被美国和日本的研究纠正。 |

Chlortetracycline is an analog of tetracycline , a broad spectrum antibiotic. In addition to its actions against microorganisms, chlortetracycline suppresses inflammation by inhibiting neutrophil action and other aspects of the innate immune response. 4-epi-Chlortetracycline is an epimer of chlortetracycline. |

Epitetracycline is an epimer of the antibiotic tetracycline . Epimers of tetracycline form without catalysis and are considered degradation products. Epitetracycline has decreased activity as an antibiotic or a Tet repressor effector but may have stronger toxic effects in animals. |

5(S),12(S)-DiHETE is a natural bioactive lipid derived from arachidonic acid . It is synthesized by glycogen-induced rabbit peritoneal polymorphonuclear leukocytes (PMNLs) incubated with AA. 5(S),12(S)-DiHETE can be produced by successive oxygenation of AA by 5-lipoxygenase (5-LO) in platelets and 12-LO in leukocytes. It can also be synthesized from 12(S)-HETE by 5-LO, in the presence of 5-LO activating protein (FLAP), activated with calcium ionophore. 5(S),12(S)-DiHETE is an epimer of leukotriene B4 that is weakly chemotactic for PMNL. |

11β-PGE2 is the C-11 epimer of PGE2. It is a moderate inhibitor of PGE2 binding to rat hypothalamic membranes with a Ki value of 53 nM.[1] 11β-PGE2 also stimulates bone resorption in rats at concentrations of 10-8 to 10-6 M which is similar to PGE2.2 11β-PGE2 inhibits PGE2 binding to the prostaglandin transporter protein with a Ki of 56 nM.[3]
