Abstract
In continuation of our reserach for synthesizing heterocyclic derivatives with a broad range of biological activities, the current research was performed to synthesize 3β-hydroxypregn-5-ene-20-one derivatives of coumarin, isoxazole, pyrazole, pyridine and pyrimidine and screen for antitumor activity. Synthesis of amino-thiopephen derivatives (1a-1b) was performed through reaction of 3β-hydroxypregn-5-ene-20-one with ethyl cyanoacetate or malononitrile and sulphur. 3β-Hydroxypregn-5-ene-20-one was reacted with ethyl cyanoacetate in the presence of hydrazine, urea or thiourea to obtain aminopyrazole (3), aminopyrimidine (4a-4b) derivatives, respectively. The amino-thiophene derivatives (1a-1b) further reacted with either phenylisothiocyanate or benzoylisothiocyanate to form fused thienopyrimidine derivatives (5a-5d). The products 1a and 1b were also treated with ethyl cyanoacetate to afford cyanoacetamidothiophene derivatives (6a-6b) which were converted to fused thienopyridone derivatives (7a-7b) through cyclization reaction. The compounds 6a and 6b were allowed to react with different carbonyl compounds including salicyaldehyde, cyclopentanone-sulphur mixture, acetylacetone and malonaldehyde to prepare coumarin (8a-8b), cyclopentylthiophene (9a-9b) and 2-pyridinone (10a-10d) derivatives respectively. Furthermore, the reactions of hydroxylamine hydrochloride and benzoylacetonitrile with the compounds 6a-6b separately afforded new aminoisoxazole (12a-12b) and phenylpyridone (14a-14b) derivatives, respectively. The structures of new products were established through IR, 1H NMR, 13C NMR spectroscopic and mass spectrometric analysis. The synthesized compounds (1a-1b to 14a-14b) displayed in-vitro antitumor activity against human cell-lines, including MCF-7 (breast adenocarcinoma), SF-268 (CNS cancer) and NCI-H460 (non-small lung cancer cell). The results suggested that all the screened products exhibited cell growth inhibitory activity in a dose-dependents manner. However, the compound 12a showed highest level of inhibition against all three cell-lines.
期刊介绍:
The international journal of the Polish Pharmaceutical Society is published in 6 issues a year. The journal offers Open Access publication of original research papers, short communications and reviews written in English, in all areas of pharmaceutical sciences. The following areas of pharmaceutical sciences are covered: Analysis, Biopharmacy, Drug Biochemistry, Drug Synthesis, Natural Drugs, Pharmaceutical Technology, Pharmacology and General.
A bimonthly appearing in English since 1994, which continues “Acta Poloniae Pharmaceutica”, whose first issue appeared in December 1937. The war halted the activity of the journal’s creators. Issuance of “Acta Poloniae Pharmaceutica” was resumed in 1947. From 1947 the journal appeared irregularly, initially as a quarterly, then a bimonthly. In the years 1963 – 1973 alongside the Polish version appeared the English edition of the journal. Starting from 1974 only works in English are published in the journal. Since 1995 the journal has been appearing very regularly in two-month intervals (six books a year). The journal publishes original works from all fields of pharmacy, summaries of postdoctoral dissertations and laboratory notes.
