The research aimed to synthesize a series of N'-substituted 1,4-benzodiazepine-1-carbothioamides (2a-j) and investigate their anti-HIV activity. The researchers used a precursor, 1,4-benzodiazepine 11, and reacted it with various N-substituted isothiocyanates or sodium thiocyanate-trifluoroacetic acid to create the target compounds. Key chemicals involved in the synthesis included 2-aminobenzyl alcohol, di-tert-butyl dicarbonate, carbon tetrabromide, triphenylphosphine, L-alanine, and different isothiocyanates. Despite the structural resemblance of these molecules to the potent TIBO-type anti-HIV compound R82150, none of the synthesized compounds displayed anti-HIV activity in vitro, suggesting that the potent anti-HIV activity of TIBO derivatives requires an intact tricyclic structure.
