Leucettamine B is a natural product found in marine sponge Leucetta microraphis. Several of analogs of its family, such as aplysinopsine and clathridine, are medicinally active molecules which have applications in many pharmaceuticals and healthcare products; however, thus far, leucettamine B has not been studied. In this report, we describe the synthesis of a new class of analogs of leucettamine B obtained by Knoevenagel condensation using a microwave reactor. The 25 newly synthesized compounds were tested against MDA-MB-468, SW480, and Mahlavu cell lines for anticancer activity. Among them, the carborane-based compound (Z)-5-(benzo[d][1,3]dioxol-5-ylmethylene)-3-(1-closo-carboranyl)-2-thioxo -thiazolidin-4-one (49) and (Z)-5-(benzo[d][1,3]dioxol-5-ylmethylene)-3-(2-(pyrrolidin-1-yl)ethyl)-2-thioxothiazolidin-4-one (31) derivatives were found to have the most potential for use against tumor cells. The carborane derivative 49 had the lowest IC50 value against the SW480 cell line (4.7 μM) and the Mahlavu (6.6 μM) cell line. Furthermore, compound 31 also had a low IC50 value against SW480 (7.5 μM). Our research shows that leucettamine B analogs might have potential for use in cancer chemotherapy.

A highly efficient domino aza-MIRC (Michael Induced Ring Closure) reaction between barbiturate-derived alkenes and N-alkoxy α-haloamides has been achieved in moderate to excellent yields. This reaction proceeds smoothly under mild conditions via a domino aza-Michael addition/intramolecular SN2 sequence, providing a practical tool in the synthesis of bioactive molecules spirobarbiturate-3-pyrrolidinones.

A facile and clean synthesis of pyrimidine derivatives via three-component reaction in aqueous Media
Shi, Daqing,Shi, Jingwen,Rong, Shaofeng
experimental part, p. 791 - 796 (2010/11/02)
A series of 5-benzylidenepyrimidine-2,4,6(1H,3H,5H)-trione and 5,5'-(arylmethylene) bis[6-aminopyrimidine-2,4(1H,3H)-dione] derivatives were synthesized via the three-component reactions of aromatic aldehyde, 6-aminopyrimidine-2,4-dione and Medrum's acid in aqueous media in the presence of triethylbenzylammonium chloride. The structures of the products were affected by substituents of aromatic aldehydes.
