We report the discovery of a new bioorthogonalclick‐and‐release reaction involving iminosydnones and strained alkynes. This transformation leads to two products resulting from the ligation and fragmentation of iminosydnones under physiological conditions. Optimized iminosydnones were successfully used to design innovative cleavable linkers for protein modification, thus opening up new areas in the
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.
