The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 2,5-Diphenyloxazole(SMILESS: C1(C2=CC=CC=C2)=NC=C(C3=CC=CC=C3)O1,cas:92-71-7) is researched.Recommanded Product: 56621-48-8. The article 《Synthesis and evaluation of trypanocidal activity of derivatives of naturally occurring 2,5-diphenyloxazoles》 in relation to this compound, is published in Bioorganic & Medicinal Chemistry. Let’s take a look at the latest research on this compound (cas:92-71-7).
African trypanosomiasis is a zoonotic protozoan disease affecting the nervous system. Various natural products reportedly exhibit trypanocidal activity. Naturally occurring 2,5-diphenyloxazoles present in Oxytropis lanata, and their derivatives, were synthesized. The trypanocidal activities of the synthesized compounds were evaluated against Trypanosoma brucei brucei, T. b. gambiense, T. b. rhodesiense, T. congolense, and T. evansi. Natural product 1 exhibited trypanocidal activity against all the species/subspecies of trypanosomes, exhibiting half-maximal inhibitory concentrations (IC50) of 1.1-13.5 μM. Modification of the oxazole core improved the trypanocidal activity. The 1,3,4-oxadiazole (7) and 2,4-diphenyloxazole (9) analogs exhibited potency superior to that of 1. However, these compounds exhibited cytotoxicity in Madin-Darby bovine kidney cells. The O-methylated analog of 1 (12) was non-cytotoxic and exhibited selective trypanocidal activity against T. congolense (IC50 = 0.78 μM). Structure-activity relationship studies of the 2,5-diphenyloxazole analogs revealed aspects of the mol. structure critical for maintaining selective trypanocidal activity against T. congolense.
