Structure and Computational Studies of New Sulfonamide Compound: {(4-nitrophenyl)sulfonyl}tryptophan.

Synthesis of sulfonamide through an indirect method that avoids contamination of the product with no need for purification has been carried out using the indirect process. Here, we report the synthesis of a novel sulfonamide compound, ({4-nitrophenyl}sulfonyl)tryptophan (DNSPA) from 4-nitrobenzenesulphonylchloride and L-tryptophan precursors. The slow evaporation method was used to form single crystals of the named compound from methanolic solution.

Novel Dipeptides Bearing Sulfonamide as Antimalarial and Antitrypanosomal Agents: Synthesis and Molecular Docking.

Objective: Currently, there is a problem of ineffective chemotherapy to trypanosomiasis and the increasing emergence of malaria drug-resistant parasites. The research aimed at the development of new dipeptide-sulfonamides as antiprotozoal agents.

Background: Protozoan parasites cause severe diseases, with African human trypanosomiasis (HAT) and malaria standing on top of the list.
