  Inhibition of estrone sulfatase by aromatase inhibitor-based estrogen 3-sulfamates

  摘要：

  our rationale is based on the finding that estrone 3-sulfamate (EMATE, 2d), a typical estrone sulfatase (ES) inhibitor, can be hydrolyzed and the pharmacological effect of the free estrogen contributes to the bioactivity of the sulfamate. A number of 3-sulfamoylated derivatives of the good aromatase inhibitors, 2- and 4-halogeno (F, Cl, and Br) estrones and their estradiol analogs as well as 6 beta-methyl and phenyl estrones, were synthesized and evaluated as inhibitors of ES in human placental microsomes in comparison with the lead compound EMATE. Among them, 2-chloro- and 2-bromoestrone 3-sulfamates (2b and 2c), along with their estradiol analogs 3b and 3c, were powerful competitive inhibitors with K-i's ranging between 4.0 and 11.3 nM (K-i for EMATE, 73 nM). These four sulfamates as well as the 2-fluoro analogs 2a and 3a inactivated ES in a time-dependent manner more efficiently than EMATE, and 2-halogeno estrone sulfamates 2 also caused a concentration-dependent loss of ES activity. The results may be useful for developing a new class of drugs having a dual function, ES inhibition and aromatase inhibition, for the treatment of breast cancer. (c) 2006 Elsevier Inc.

  雌激素-3-邻氨基磺酸雌酮类似物作为强效类固醇硫酸酯酶抑制剂的合成与评价

  摘要：

  氨基磺酸雌酮（EMATE）是一种强力不可逆的甾族硫酸酯酶（STS）抑制剂。为了进一步扩大SAR，将该化合物在2-和/或4-位取代，并且还除去其17-羰基。对于两个衍生物，在两个体外系统中观察到针对STS的以下一般效力顺序：4-NO 2  > 2-卤素，2-氰基> EMATE（未取代）> 17-脱氧EMATE> 2-NO 2  > 4-溴> 2-（2-丙烯基），2-正丙基> 4-（2-丙烯基），4-正丙基> 2,4-（2-丙烯基）= 2,4-二-n-丙基。将吸电子取代基放置在A环上具有明显的优势，而卤素优选在2位上，而硝基在4位上。在EMATE的2-和/或4-位上用2-丙烯基或正丙基取代，以及除去17-羰基对效能是有害的。设计的三种环状氨基磺酸盐不是STS抑制剂。这进一步证实，如EMATE和Irosustat抑制剂所示，游离或N-未取代的氨基磺酸酯基团（H 2 NSO 2 O–）是有效和不可

  Efficient and flexible syntheses of 2-substituted estrone, estradiol and their 3-O-sulfamate (EMATE) derivatives have been developed using directed ortho-lithiation methodology. 2-Substituted EMATEs display a similar antiproliferative activity profile to the corresponding estradiols against a range of human cancer cell lines. 2-Methoxy (3, 4), 2-methylsulfanyl (20, 21) and 2-ethyl EMATEs (32, 33) proved the most active compounds with 2-ethylestradiol-3-O-sulfamate (33), displaying a mean activity over the NCI 55 cell line panel 80-fold greater than the established anticancer agent 2-methoxyestradiol (2). 2-Ethylestradiol-3-O-sulfamate (33) was also an effective inhibitor of angiogenesis using three in vitro markers, and various 2-substituted EMATEs also proved to be inhibitors of steroid sulfatase (STS), a therapeutic target for the treatment of hormone-dependent breast cancer. The potential of this novel class of multimechanism anticancer agents was confirmed in vivo with good activity observed in the NCI hollow fiber assay and in a MDA-MB-435 xenograft mouse model.

  Estrone sulfamate (EMATE) is a potent irreversible inhibitor of steroid sulfatase (STS). In order to further expand SAR, the compound was substituted at the 2- and/or 4-positions and its 17-carbonyl group was also removed. The following general order of potency against STS in two in vitro systems is observed for the derivatives: The 4-NO2 > 2-halogens, 2-cyano > EMATE (unsubstituted) > 17-deoxyEMA
