Synthesis and biomedicinal investigation of novel styryl lactone and antitumor agent tiazofurin bioisosteres

Abstract

<p>U ovom radu prikazana je sinteza 11 tiazolnih izostera goniofufurona (1-11),<br />4 konformaciono kruta analoga goniofufurona (12-15) i jednog butadiolnog<br />derivata&nbsp; tiazofurina&nbsp; (16).&nbsp; Takođe,&nbsp; izvr&scaron;eno&nbsp; je&nbsp; ispitivanje&nbsp; i&nbsp; poređenje<br />biolo&scaron;kih&nbsp; aktivnosti&nbsp; sintetisanih&nbsp; analoga&nbsp; sa&nbsp; sa&nbsp; aktivno&scaron;ću&nbsp; i&nbsp; selektivno&scaron;ću<br />kako GF i TF tako i doksorubicina, jedinjenja &scaron;irokog spektra dejstva (DOX).<br />Hiralni&nbsp; prekursor&nbsp; novosintetisanih&nbsp; jedinjenja&nbsp; 1-15&nbsp; bila&nbsp; je&nbsp; D-glukoza,&nbsp; a<br />jedinjenja 16 D-arabinoza.</p>

<p>A multistep synthesis of 11 novel thiazole isosteres of goniofufurone (1-11), 4 novel conformationally constrained isosteres of goniofufurone (12-15), as well as&nbsp; one&nbsp; butanediole&nbsp; derivative&nbsp; of&nbsp; tiazofurin&nbsp; (16)&nbsp; has&nbsp; been&nbsp; achieved.&nbsp; In&nbsp; vitro cytotoxicity of newly synthetized derivatives has been evaluated and compared with the cytotoxicities of goniofufurone, tiazofurin and doxorubicin.</p>
