Design, synthesis and antiproliferative activity studies of 1,2,3-triazole-chalcones

A series of 1,2,3-triazole-chalcone hybrids were designed, synthesized and evaluated for their antiproliferative activity against three selected cancer cell lines (SK-N-SH, HepG-2 and MGC-803). Most of the synthesized compounds exhibited moderate to good activity against all the cancer cell lines selected. Particularly, compound 12k showed the most excellent antiproliferative activity with an IC50 value of 1.53 μM against SK-N-SH cancer cells. The mechanism studies revealed that compound 12k inhibited the proliferation of SK-N-SH cancer cells by inducing apoptosis and arresting the cell cycle at the G1 phase.

One-pot preparation of pyrrole derivatives via the copper-catalyzed [4+1] annulation of propargylic amines with ethyl glyoxylate and phenylglyoxal in the presence of piperidine

We describe how copper(II) chloride efficiently catalyzes the [4+1] annulation of propargylamines with either ethyl glyoxylate or phenylglyoxal functioning as a C1 unit, in the presence of piperidine, which leads to a straightforward and one-pot preparati

Copper(II)-Catalyzed [4+1] annulation of propargylamines with N,O-acetals: Entry to the synthesis of polysubstituted pyrrole derivatives

Described herein is the CuCl2-catalyzed [4+1] annulation of a variety of propargylamines with N,O-acetals that function as a C1 unit, leading to the production of polysubstituted pyrrole derivatives. Three important features of the N,O-acetal during the [4+1] annulation series via 5-endo-dig cyclization are described: an enolizable substituent adjacent to the central sp3-carbon is required, the central sp3-carbon displays the functions of both an electrophile and a nucleophile, and liberation of the secondary amine smoothly leads to the aromatization. A CuCl2-catalyzed [4+1] annulation of propargylamines with N,O-acetals having an ester, a ketone, and an amide moiety, leading to the facile preparation of polysubstituted pyrrole derivatives is presented. This annulation series was achieved through 5-endo-dig cyclization and subsequent aromatization in one pot.

Palladium-catalyzed cleavage of O/N-propargyl protecting groups in aqueous media under a copper-free condition

(Figure presented) A copper-free palladium-mediated cleavage of O/N-propargyl bonds in aqueous media has been investigated, affording a mild and convenient method for the deprotection of phenols and anilines. The methodology could be utilized for the selective removal of propargyl groups from aryl ethers and amines without affecting a variety of unprotected functional groups present in the substrates. The mechanism and scope of the reaction is discussed.

Potent inhibition of thymidylate synthase by two series of nonclassical quinazolines

The synthesis and biological activity of two series of nonclassical thymidylate synthase (TS) inhibitors are described. The first is a series of 10-propargyl-5.8-dideazafolic acid derivatives (10a-j) and the second is a series of the analogous 2-desamino

Substituted quinazolinones as anticancer agents

Novel 6-substituted-4(3H)-quinazolinones are described as well as methods for the preparation and pharmaceutical composition of same, which inhabit the enzyme thymidylate synthase (TS) and are thus useful as anticancer agents.
