Abstract
Substituted and/or heterocyclic d-homoestrone derivatives were synthetized via the intramolecular cyclization of a δ-alkenyl-d-secoaldehyde, -d-secoalcohol or -d-secocarboxylic acid of estrone 3-benzyl ether. The d-secoalcohol was modified at three sites in the molecule. The in vitro antiproliferative activities of the new d-homo- and d-secoestrone derivatives were determined on HeLa, MCF-7, A431 and A2780 cells through use of MTT assay. d-Homoalcohols 3 and 5 displayed cell line-selective cytostatic effects against ovarian and cervical cell lines, respectively. Two d-secoestrones (6 and 12c) proved to be effective, with IC50 values comparable with those of the reference agent cisplatin. A selected compound (6) was tested by tubulin polymerization assay and its cancer specificity was additionally determined by using noncancerous human fibroblast cells.

Abstract
During recent years intensive research has been focused on the synthesis of structurally modified steroid hormones in order to obtain compounds with beneficial biological activity such as cell-growth inhibition. Experimental results have revealed that some steroidal derivatives possess direct cytostatic effect on cancer cells in a hormone receptor-independent manner. After a brief account on the most important biological function and characteristics of the naturally occurring sex hormones in physiological and pathological conditions, structural modifications of estrane and androstane scaffolds are discussed in detail. The review covers literature publications (from 2002 to 2012) relating to the synthesis and antiproliferative activity of semisynthetic sex hormone-derived molecules containing simple or heterocyclic substituents. The compounds reviewed are divided into three main categories according to their sterane framework and the nature of substitution. This article is part of a Special Issue entitled "Synthesis and biological testing of steroid derivatives as inhibitors".

Synthesis and investigation of the anticancer effects of estrone-16-oxime ethers in vitro. Steroids 2013; 78:69-78. [PMID: 23127813 DOI: 10.1016/j.steroids.2012.10.009] [Citation(s) in RCA: 48] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/27/2012] [Revised: 09/28/2012] [Accepted: 10/10/2012] [Indexed: 11/21/2022]
Abstract
An expanding body of evidence indicates the possible role of estrane derivatives as useful anticancer agents. The aim of this study was to describe the cytotoxic effects of 63 newly synthetized estrone-16-oxime ethers on human cancer cell lines (cervix carcinoma HeLa, breast carcinoma MCF7 and skin epidermoid carcinoma A431), studied by means of the MTT assay. Four of the most promising compounds were selected for participation in additional experiments in order to characterize the mechanism of action, including cell cycle analysis, morphological study and the 5-bromo-2'-deoxyuridine incorporation assay. The cancer selectivity was tested on a noncancerous fibroblast cell line (MRC-5). Since apoptosis and cell cycle disturbance were observed, caspase-3 activities were further assayed for the two most effective agents. These estrone-16-oxime analogs activated caspase-3 and changed the mRNA level expression of endogenous factors regulating the G1-S phase transition (retinoblastoma protein, CDK4 and p16). The repression of retinoblastoma protein was reinforced at a protein level too. These experimental data lead to the conclusion that estrone-16-oxime ethers may be regarded as potential starting structures for the design of novel anticancer agents.

Abstract
Many different glycoconjugates, including saponins (e.g., hellebrin) and anthracyclines (e.g., doxorubicin), are known to display cytotoxic activities. In recent work, we have developed synthetic protocols for the synthesis of various glycoconjugates, focusing on glycosylation methods for different classes of biomolecules. Simultaneously a number of saponins and anthracyclines have been generated. In this note, the cytotoxic activities of these synthesized compounds are briefly addressed.
