Design and synthesis of 1,3-biarylsulfanyl derivatives as new anti-breast cancer agents
摘要:
A new series of 1,3-biarylsulfanyl derivatives (homodibenzyl core motif) have been designed and synthesized as new estrogen receptor ligands by chopping benzothiophene core of raloxifene to engender secoraloxifene scaffold. All the synthesized compounds were screened for anti-proliferative, anti-osteoporotic, and anti-implantation activity. Compounds (35, 36) having basic amino anti-estrogenic side chain were exhibiting potential anti-proliferative activity in MCF-7, MDA-MB-231 and ishikawa cell lines. Some of the synthesized compounds having homodibenzyl motif (5, 8, 10) have shown moderate anti-osteoporotic activity. (C) 2011 Elsevier Ltd. All rights reserved.

Here, we have demonstrated the Michael addition of active methylene compounds, aromatic/aliphaticamines, thiols and alcohols to conjugated alkenes using magnetic nano-NiFe2O4 as reusable catalyst in water. Nano-NiFe2O4 efficiently catalyzed the formation of C–C and C–X (X = N, S, O etc.) bond through 1,4-addition reactions.
在这里,我们已经证明了使用磁性纳米NiFe 2 O 4作为在水中可重复使用的催化剂将活性亚甲基化合物,芳香族/脂肪族胺,硫醇和醇的迈克尔加成到共轭烯烃上。纳米NiFe 2 O 4通过1,4-加成反应有效催化了CC和CX (X = N,S,O等)键的形成。
