2-chloroethylnitrososulfamides (CENS) was studied in aqueous bufferedsolutions with pH ranging from0 to 14. The study was monitored by RP-LC-MS and conventional UV spectrophotometry. The reaction proceeded via a pseudo-first-order kinetic with significant correlation coefficient. The major decomposition products from CENS after incubation in phosphatebuffer were isolated and identified by NMR and mass spectrometry
A new family of potential oncostatics: 2-chloroethylnitrososulfamides (CENS)—I. Synthesis, structure, and pharmacological evaluation (preliminary results)
A new series of alkylating agents, 2-chloroethylnitrososulfamides (CENS), were developed on the model of 2-chloroethylnitrosoureas. Starting from chlorosulfonyl isocyanate, a four-step synthesis (carbamoylation-sulfamoylation, Mitsunobu alkylation, deprotection, and nitrosation) gives the title compounds in a 47-58% overall yield. The selection of the nitrosation site can be directed through an alternative route. The pharmacological evaluation shows a significant oncostatic activity towards both A549 and MCF7 cell lines.
