The article was titled 《Structure activity refinement of phenylsulfonyl piperazines as antimalarials that block erythrocytic invasion》, and you may find the article in European Journal of Medicinal Chemistry.Synthetic Route of C5H12N2 The information in the text is summarized as follows:
The optimization and further characterization of the phenylsulfonyl piperazine class I [R = 4-Me, 3-t-Bu, 4-Br, etc.; R1 = pyrrolidin-1-yl, piperidin-1-yl, 1,2,3,4-tetrahydroisoquinolin-2-yl, etc.; X = -(N(CH2)2N(CH2)2)-CH(CH3), -(NCH(CH3)N(CH2)2)-CH(CH3), -(NC(CH3)2N(CH2)2)-CH(CH3), etc.] was described. During the optimization process the functionality required for P. falciparum asexual stage activity was defined and determined the alpha-carbonyl S-Me isomer was important for antimalarial potency. The optimized compounds I also possessed comparable activity against multidrug resistant strains of P. falciparum and displayed weak activity against sexual stage gametocytes. The optimized compounds I blocked erythrocyte invasion consistent with the asexual activity observed and therefore the phenylsulfonyl piperazine analogs described could serve as useful tools for studying Plasmodium erythrocyte invasion. After reading the article, we found that the author used 1-Methylpiperazine(cas: 109-01-3Synthetic Route of C5H12N2)
1-Methylpiperazine(cas: 109-01-3) can be used as mimic template in the preparation of molecularly imprinted microspheres (MIMs). It was also used to prepare the difunctional strong anion-exchange stationary phase from a 1,4-diazacyclohexane derivative..Synthetic Route of C5H12N2
