effective at 0.1 mg mL−1 in the cell-free assay and 0.5 mg mL−1 in the cell-associated assay. Compound 1(16) shows the best combination of dual activity against sperm and HIV. In summary, hydroxylated cationic surfactants, 1 and 2, show promise as inexpensive topical, contraceptive microbicides.
2-羟基-N-(2-羟乙基)-N,N-二甲基-1-烷胺1(p)和2-羟基-N,N-双(2-羟乙基)-N-甲基-1- alkanaminium 2(p为同源系列中描述)溴化物,tetradecanaminium(p = 14)通过octadecaminium(p= 18)。该系列偶数成员的临界胶束浓度(cmc's)在25和37°C下通过电导率测量,显示了预期的线性依赖于链长。所有化合物均显示杀精和杀虫活性。在Sander–Cramer杀虫剂测定法1和2中,最小有效浓度(MEC)与链长的关系图分别显示了截止效应和抛物线关系。最好的化合物1(17)和1(18)的MEC(〜0.12 mg mL -1)略低于市售杀精子剂壬氧化酚9(N-9)。化合物1(16)和2(17)在体外,无细胞和细胞相关的病毒灭活试验中显示出最佳的抗HIV活性。两者在无细胞测定中均为0.1 mg mL -1,在细胞相关测定中均为0
