PI3Kα-IN-4 is a potent, selective, and orally active PI3Kα inhibitor with an IC50 of 1.8 nM, demonstrating antitumor activity [1].

PMX-205 is a cyclic hexapeptide that acts as a potent antagonist of C5a receptor (C5aR; IC50= 31 nM).1It is orally active and blocks inflammatory signaling and symptoms in animal models of colitis and allergic asthma.2,3PMX-205 is also brain penetrant and reduces neuroinflammation and neurodegeneration in an animal model of Alzheimer's disease.4 1.March, D.R., Proctor, L.M., Stoermer, M.J., et al.Potent cyclic antagonists of the complement C5a receptor on human polymorphonuclear leukocytes.

NG 25 is a type II kinase inhibitor that inhibits MAP4K2 and TAK1 (IC50s = 21.7 and 149 nM, respectively).1It also inhibits the Src family kinases Src and LYN (IC50s = 113 and 12.9 nM, respectively) and Abl family kinases (IC50s = 75.2 nM), as well as CSK, FER, and p38α (IC50s = 56.4, 82.3, and 102 nM, respectively). NG 25 (100 nM) prevents TNF-α-induced IKKα/β phosphorylation and IκB-α degradation in L929 cells. It inhibits secretion of IFN-α and IFN-β induced by CpG type B and CL097, respectively, in Gen2.2 cells in a concentration-dependent manner.2NG 25 decreases cell viability of HCT116KRASWT, and to a greater degree of HCT116KRASG13D, colorectal cancer cells in a concentration-dependent manner.3It also reduces tumor growth and increases the number of TUNEL-positive tumor cells in a CT26KRASG12Dmouse orthotopic model of colorectal cancer. 1.Tan, L., Nomanbhoy, T., Gurbani, D., et al.Discovery of type II inhibitors of TGFβ-activated kinase 1 (TAK1) and mitogen-activated protein kinase kinase kinase kinase 2 (MAP4K2)J.

Novel oxylipins, referred to as docosanoids, have been derived from C22polyunsaturated fatty acids 7(S),17(S)-dihydroxy-8(E),10(Z),13(Z),15(E),19(Z)-Docosapentaenoic acid (7(S),17(S)-hydroxy DPA) is a DPA-derived analog of the 17(S)-dihydroxy series of docosanoids known as protectins. Protectin D1, a DHA-derived dihydroxy fatty acid, exhibits potent anti-inflammatory activities.1,2,3Potentially, 7(S),17(S)-hydroxy DPA demonstrates similar properties; however, its biological activity has yet to be determined. 1.Serhan, C.N., Gotlinger, K., Hong, S., et al.Anti-inflammatory actions of neuroprotectin D1/protectin D1 and its natural stereoisomers: Assignments of dihydroxy-containing docosatrienesJ.

Rec 15/2615 is an antagonist of α1B-adrenergic receptors (α1B-ARs; Ki = 0.45 nM for the recombinant human receptor).1 It selectively inhibits α1B-ARs over α1A-, α1D-, and α1L-ARs (Kis = 7.59, 10.23, and 49 nM, respectively). Rec 15/2615 inhibits norepinephrine-induced contractions of isolated rabbit prostate and urethral strips (Kis = 100 and 316.2 nM, respectively), as well as reduces norepinephrine-induced contractions of chloroethylclonidine-precontracted isolated rabbit aortic rings (Ki = 50 nM).2 It decreases diastolic blood pressure (ED25 = 183 μg/kg, i.v.) and increases intracavernous pressure in anesthetized dogs when administered intracavernously at doses ranging from 30 and 1,000 μg/kg.1,2 |1.
