Synthesis, Characterization and Biological Activity of Some Dithiourea Derivatives
Abstract:
Novel dithiourea derivatives have been designed as HIV-1 protease inhibitors using Autodock 4.2, synthesized and characterized by spectroscopic methods and microanalysis. 1-(3-Bromobenzoyl)-3-[2-([(3-bromophenyl)formami-do]methanethioylamino)phenyl]thiourea (10) and 3-benzoyl-1[(phenylformamido)methanethioyl]aminothiourea (12) gave a percentage viability of 17.9 ± 5.6% and 11.2 ± 0.9% against Trypanosoma brucei. Single crystal X-ray dif-fraction analysis of 1-benzoyl-3-(5-methyl-2-[(phenylformamido)methanethioyl]aminophenyl)thiourea (1), 3-ben-zoyl-1-(2-[(phenylformamido)methanethioyl]aminoethyl)thiourea (11), 3-benzoyl-1-[(phenylformamido)methan-ethioyl]aminothiourea (12) and 3-benzoyl-1-(4-[(phenylformamido)methanethioyl]aminobutyl)thiourea (14) have been presented. 1-(3-Bromobenzoyl)-3-[2-([(3-bromophenyl)formamido]methanethioylamino)phenyl]thiourea (10) gave a percentage inhibition of 97.03 ± 0.37% against HIV-1 protease enzyme at a concentration of 100 ?M.
