  新型紫杉烷类口服药物的合成

  摘要：

  合成了一组在紫杉醇的C-7，C-10，C-3'和C-14位置进行了修饰的新型类紫杉醇，以通过降低它们与P-糖蛋白（P-gp）的亲和力来改善其生物学特性）并增加细胞通透性。在体外，大多数新的类紫杉醇在MCF-7人肿瘤细胞系中表现出与紫杉醇相似的有效细胞毒性活性。在单层Caco-2细胞的通透性测定中，与紫杉醇相比，大多数化合物在A到B方向上表现出增加的跨细胞转运。其中的化合物T - 13，T - 15和T - 26表现出最高的渗透性，并且其流出率比Ortataxel更好。使用Madin-Darby犬肾（MDCK）-多药耐药-1（MDR1）和MDCK-野生型（WT）评估化合物T - 13和T - 26与P-gp的相互作用。结果表明，T - 13和T - 26是P-gp的底物，具有P-gp介导的外排的抑制作用。因此很明显，紫杉醇在C-7，C-10和C-3'位置的同时修饰显着削弱了其与P-gp的相互作用，并干扰了P-gp介导的外排。

  3′-difluorovinyl taxoids evaluated, eight taxoids exhibited less than 100 pM IC50 values against MCF7 cell line. Difluorovinyl taxoids induced GTP-independent tubulin polymerization much faster than paclitaxel. Then, the resulting microtubules were stable to Ca2+-induced depolymerization, indicating strong stabilization of microtubules. Molecular modeling study indicated that a difluorovinyl taxoid binds to

  A series of novel taxane-based multidrug resistance (MDR) reversal agents (TRAs) has been designed and synthesized. Structure-activity relationship (SAR) study clearly indicates that modification of the C-7 position with hydrophobic arenecarbonyleinnamoyl groups brings about high potency against drug efflux mediated by P-glycoprotein (P-gp). Six TRAs exhibit ability to modulate a wide range of ATP-binding cassette (ABC) transporters, such as P-gp, multidrug resistance-associated protein 1 (MRP1), and breast cancer resistance protein (BCRP), which may serve as novel broad-spectrum modulators of ABC transporters.

  A series of new 3'-(2-methyl-1-propenyl) and 3'-(2-methylpropyl) taxoids with modifications at C-10 was synthesized by means of the beta-lactam synthon method using 10-modified 7-(triethylsilyl)-10-deacetylbaccatin III derivatives. The new taxoids thus synthesized show excellent cytotoxicity against human ovarian (A121), non-small-cell lung (A549), colon (HT-29), and breast (MCF-7) cancer cell lines. All but one of these new taxoids possess better activity than paclitaxel and docetaxel in the same assay, i.e., the IC50 values of almost all the taxoids are in the subnanomolar level. It is found that a variety of modifications at C-10 is tolerated for the activity against normal cancer cell lines, but the activity against a drug-resistant human breast cancer cell line expressing MDR phenotype (MCF7-R) is highly dependent on the structure of the C-10 modifier. A number of the new taxoids exhibit remarkable activity (IC50 = 2.1-9.1 nM) against MCF7-R. Among these, three new taxoids, SB-T-1213 (4a), SB-T-1214 (4b), and SB-T-1102 (5a), are found to be exceptionally potent, possessing 2 orders of magnitude better activity than paclitaxel and docetaxel. The observed exceptional activity of these taxoids may well be ascribed to an effective inhibition of P-glycoprotein binding by the modified C-10 moieties. The new taxoid SB-T-1213 (4a) shows an excellent activity (T/C = 0% at 12.4 and 7.7 mg/kg/dose, log(10) cell kill = 2.3 and 2.0, respectively) against B16 melanoma in B6D2F(1) mice via intravenous administration.
