Synthesis and molecular modelling studies of phenyl linked oxadiazole-phenylhydrazone hybrids as potent antileishmanial agents
摘要:
Molecular hybridization yielded phenyl linked oxadiazole-benzohydrazones hybrids 6-35 and were evaluated for their antileishmanial potentials. Compound 10, a 3,4-dihydroxy analog with IC50 value of 0.95 +/- 0.01 mu M, was found to be the most potent antileishmanial agent (7 times more active) than the standard drug pentamidine (IC50 = 7.02 +/- 0.09 mu M). The current series 6-35 conceded in the identification of thirteen (13) potent antileishmanial compounds with the IC50 values ranging between 0.95 +/- 0.01-78.6 +/- 1.78 mu M. Molecular docking analysis against pteridine reductase (PTR1) were also performed to probe the mode of action. Selectivity index showed that compounds with higher number of hydroxyl groups have low selectivity index. Theoretical stereochemical assignment was also done for certain derivatives by using density functional calculations. (C) 2016 Elsevier Masson SAS. All rights reserved.

In the search of potent antidiabetic drug, we synthesized 1-25 2-(2-methoxyphenyl)-5-phenyl-1,3,4-oxadiazole derivatives. First, we synthesized 2-methoxybenzohydrazide from methyl 2-methoxybenzoate which was treated with different arylaldehydes to afford 1-25 compounds. The synthesized compounds were evaluated for antiglycation activity. We found that 1-6 and 8 showed potent activity ranging from 160.2 to 290.17 A mu M better than standard drug rutin (IC50 = 295.09 +/- A 1.04 A mu M). All the synthesized compounds were characterized by different spectroscopy methods. These compounds can further be studied to develop lead antidiabetic compounds.
