Ureido-substituted sulfamates show potent carbonic anhydrase IX inhibitory and antiproliferative activities against breast cancer cell lines
摘要:
A series of 50 sulfamates were obtained by reacting 4-aminophenol with isocyanates followed by sulfamoylation. Most of the new compounds were nanomolar inhibitors of the tumor-associated carbonic anhydrase (CA, EC 4.2.1.1) isoforms IX and XII, whereas they inhibited less cytosolic offtarget isoforms CA I and II. Some of these sulfamates showed significant antiproliferative activity in several breast cancer cell lines, such as SKBR3, MCF10A, ZR75/1, MDA-MB-361 and MCF7, constituting interesting anticancer leads.

Synthesis and DNA-cleaving activity of lactenediynes conjugated with DNA-complexing moieties
摘要:
Lactenediynes are compounds characterized by the fusion of a beta-lactam with a cyclodeca-3-ene-1,5-diyne. In this work the most promising members of this family have been activated by attaching a carbalkoxy or a carbamoyl group to the azetidinone nitrogen, and conjugated to various DNA-complexing moieties, either acting by intercalation or through groove binding. These conjugated artificial enediynes have been demonstrated to possess in vitro ability to produce single and double strand cleavage of plasmid DNA. As potency and capacity to induce double cut, they rank among the best simple enediyne analogues ever prepared. A thorough investigation was carried out in order to develop the best suited linkers for assembling these conjugates. (C) 2008 Elsevier Ltd. All rights reserved.

Various tryptamines are captured by a vinylsulfonylmethyl polystyrene resin, generating a safety-catch linkage. Beta-carbolines can be formed from 4 by a Pictet-Spengler reaction with the introduction of R(1). Tryptamine 4 can also be derivatized by acylation or copper-mediated coupling to introduce R(2). If X = Br, Suzuki coupling can be used to introduce R(3). After derivatization, the indole derivatives
