摘要:
Novel dithiourea derivatives have been designed as HIV-1 protease inhibitors using Auto dock 4.2, synthesized and characterized by spectroscopic methods and microanalysis. 1-(3-Bromobenzoyl)-3- [2-({[(3-bromophenyl)form amido] methanethioyllamino)phenyl] thiourea (10) and 3-benzoyl-1{ [(phenylformamido)methanethioyl] amino}thiourea (12) gave a percentage viability of 17.9 +/- 5.6% and 11.2 +/- 0.9% against Trypanosoma brucei. Single crystal X-ray diffraction analysis of 1-benzoyl-3-(5-methyl-2-{[(phenylformamido)methanethioyl]amino}phenyl)thiourea (1), 3-benzoyl-1- (2-{[(phenylformamido)methanethioyl]amino}ethyl)thiourea (11), 3-benzoyl-1-{[(phenylformamido)methanethioyl]amino}thiourea (12) and 3-benzoyl-1- (4-{ [(phenylformamido)methanethioyl] amino}butyl)thioure a (14) have been presented. 1-(3-Bromobenzoyl) 3 [2-({[(3-bromophenyl)formamido]methanethioyl}amino)phenyl]thiourea (10) gave a percentage inhibition of 97.03 +/- 0.37% against HIV-1 protease enzyme at a concentration of 100 mu M.
