  In vitro evaluation of phosphocholine and quaternary ammonium containing lipids as novel anti-HIV agents

  摘要：

  A series of synthetic lipids containing a two- or three-carbon backbone substituted with a thio, oxy, or amidoalkyl functionality and either a phosphocholine or quaternary ammonium moiety was evaluated as potential anti-HIV-1 agents. Several analogues were identified as possessing activity with the most promising compound being rac-3-octadecanamido-2-ethoxypropylphosphocholine (8). Compound 8 exhibited an IC50 for the inhibition of plaque formation of 0.16-mu-M which was 84-fold lower than the IC50 value determined for CEM-SS cell growth inhibition. Initial mechanistic studies have indicated that these compounds, unlike AZT, are not reverse transcriptase (RT) inhibitors, but instead appear to inhibit a late step in HIV replication involving virus assembly and infectious virus production. Since these lipids are acting via a different mechanism, they represent an alternative approach to the chemotherapeutic treatment of AIDS as well as candidates for combination therapy with AZT.

  新型的烷基甘油季铵盐衍生物作为蛋白激酶C的有效抑制剂的合成及生物活性

  摘要：

  烷基甘油，例如rac-1-O-十八烷基-2-O-甲基甘油磷酸胆碱（Et-18-OMe）对多种癌细胞系的转移和生长均显示出抑制作用。已显示烷基磷脂积聚在几种细胞系的表面，其选择性仍不清楚。该作用的结果可能导致抑制细胞膜相关蛋白激酶C（PKC）。这项研究的目的是开发PKC的醚脂质抑制剂以增强抗肿瘤活性。这导致了一系列烷基甘油的新型季铵衍生物的合成和体外测试。这些类似物在用rac-1-O-油酰基-2-O-乙酰甘油刺激的PKC上的生物学测试表明，其抑制作用与Et-18-OMe相当。

  Combinations of an amidoalkylphosphocholine, 8, and AZT have been found to cause an apparent synergistic action in suppressing infectious HIV-1 replication. In addition, amidoalkyl, oxyalkyl, and thioalkyl ether lipids have been chemically linked to anti-HIV-1 nucleosides (AZT and DDI) through phosphate and phosphonate linkages. These conjugates have shown promising in vitro anti-HIV-1 activity. Also, the conjugates have a 5-10-fold reduction in cell cytotoxicity compared to AZT alone. The most active compound, an amidoalkyl ether lipid-AZT conjugate, 4A, was found to have a differential selectivity of 1793 in a syncytial plaque assay. In comparison, AZT alone has a value of 1281.

  Novel quaternary amine ether lipids have been synthesized and tested for inhibition of neoplastic cell proliferation with the HL-60 promyelocytic leukemia cell line. These compounds contain a positively charged quaternary amine functional group attached either directly to the glycerol backbone or at the end of an alkoxy chain. The biological testing has identified several analogues with activity equivalent to or greater than that exhibited by the reference compound in this assay, ET-18-OMe (1-O-octadecyl-2-O-methyl-rac-glycero-3-phosphocholine). Among the most active analogues are compounds 11, [N,N,N-triethyl-3-(hexadecyloxy)-2-ethoxy-1-propylammonium bromide] and 22 [N-[4-[3-(hexadecyloxy)-2-ethoxypropoxy]-1-butyl]pyridinium bromide], which are approximately 3 times as active as the reference standard.
