Guanylthiourea (GTU) derivatives were identified as possible anti-malarial agents, recently, using in?vitro studies on Plasmodium falciparum. This article gives an account of the in?vivo anti-malarial activity of GTU derivatives against experimental rodent malaria. A total of 20 synthesized GTU derivatives were evaluated for in?vivo antimalarial activity, out of which six showed encouraging results; one compound appeared to have curative potential. Molecular docking and molecular dynamics analysis were carried out to understand the molecular level interactions.

Diabetes mellitus is a chronic metabolic disorder that affects more than 180 million people worldwide. Peroxisome proliferator activated receptors (PPARs) are a group of nuclear receptors that have been targeted by the thiazolidinedione (TZD) class of compounds for the management of type II diabetes. PPAR3 is known to regulate adipogenesis and glucose metabolism. Another emerging target for the design of antidiabetic agents is the free fatty acid receptor 1 (FFAR1), previously known as GPR40. Agonists of this receptor were found to enhance insulin secretion in diabetic patients. It has been reported that some thiazolidinediones (TZDs) activate FFAR1 with micromolar potency. In this study, based on docking studies into the crystal structure of PPAR3 and a homology model of FFAR1, nineteen compounds were designed, synthesized, and biologically tested for agonistic activity on both receptors. Nine compounds showed promising dual activity, with two compounds, 11a and 5b, having affinities in the low micromolar range on both targets. These molecules represent the first antidiabetic agents that could act as insulin sensitizers as well as insulin secretagogues.
Synthesis and antimicrobial evaluation of L-phenylalanine-derived C5-substituted rhodanine and chalcone derivatives containing thiobarbituric acid or 2-thioxo-4-thiazolidinone

Four novel series of compounds, including the l-phenylalanine-derived C5-substituted rhodanine (6a-q, 7a-j) and chalcone derivatives containing thiobarbituric acid or 2-thioxo-4-thiazolidinone (9a-e, 11a-e) have been designed, synthesized, characterized, and evaluated for their antibacterial activity. Some of these compounds showed significant antibacterial activity against Gram-positive bacterias, especially against the strains of multidrug-resistant clinical isolates, among which compounds 6c-e, 6g, 6i, 6j and 6q exhibiting high levels of antimicrobial activity against Staphylococcus aureus RN4220 with minimum inhibitory concentration (MIC) values of 2 μg/mL. Compound 6q showed the most potent activity of all of the compounds against all of the test multidrug-resistant clinical isolates tested. Unfortunately, however, none of the compounds were active against Gram-negative bacteria at 64 μg/mL.
Asymmetric syntheses of a GPR40 receptor agonist via diastereoselective and enantioselective conjugate alkynylation

experimental part, p. 4730 - 4737 (2010/08/06)
Two asymmetric methods to synthesize a potent GPR40 receptor agonist are reported. Both synthetic routes utilize readily available, inexpensive starting materials and reagents. The first route relies on a highly diastereoselective conjugate alkynylation of an ephedrine-derived oxazepanedione acceptor. The second route features the enantioselective alkynylation of a Meldrum's acid-derived acceptor mediated by a chiral zinc cinchonidine reagent.

(Chemical Equation Presented) The enantioselective conjugate addition of alkynyl nucleophiles has been a long-standing challenge in synthetic chemistry. This paper describes a highly practical asymmetric conjugate alkynylation of Meldrum's acid-derived acceptors using cinchonidine ($100/kg) as the chiral mediator. The process provides practical access to chiral β-alkynyl acids. Noteworthy attributes of the method are its broad scope, high functional-group compatibility, and ease of scalability. Copyright
OXADIAZOLIDINEDIONE COMPOUND

Page/Page column 47, (2009/01/24)
[Problem] A compound which can be used as a pharmaceutical, particularly a insulin secretion promoter or a agent for preventing/treating disease in which GPR40 is concerned such as diabetes or the like, is provided. [Means for resolution] It was found that an oxadiazolidinedione compound which is characterized by the possession of a benzyl or the like substituent binding to the cyclic group via a linker at the 2-position of the oxadiazolidinedione ring, or a pharmaceutically acceptable salt thereof, has excellent GPR40 agonist action. In addition, since the oxadiazolidinedione compound of the present invention showed excellent insulin secretion promoting action and blood glucose level-lowering action, it is useful as an insulin secretion promoter or an agent for preventing/treating diabetes.
