Thiazolidinediones as antidiabetic agents: A critical review

Thiazolidinediones (TZDs) or Glitazones are an important class of insulin sensitizers used in the treatment of Type 2 diabetes mellitus (T2DM). TZDs were reported for their antidiabetic effect through antihyperglycemic, hypoglycemic and hypolipidemic agents. In time, these drugs were known to act by increasing the transactivation activity of Peroxisome Proliferators Activated Receptors (PPARs). The clinically used TZDs that suffered from several serious side effects and hence withdrawn/updated later, were full agonists of PPAR-gamma and potent insulin sensitizers. These drugs were developed at a time when limited data were available on the structure and mechanism of PPARs. In recent years, however, PPAR-alpha/gamma, PPAR-alpha/delta and PPAR-delta/gamma dual agonists, PPAR pan agonists, selective PPAR-gamma modulators and partial agonists have been investigated. In addition to these, several non PPAR protein alternatives of TZDs such as FFAR1 agonism, GPR40 agonism and ALR2, PTP1B and alpha-glucosidase inhibition have been investigated to address the problems associated with the TZDs. Using these rationalized approaches, several investigations have been carried out in recent years to develop newer TZDs devoid of side effects. This report critically reviews TZDs, their history, chemistry, mechanism mediated through PPAR, recent advances and future prospects.

Novel bifunctional thiourea-ammonium salt catalysts derived from amino acids: Application to highly enantio- and diastereoselective aza-Henry reaction

The development of new efficient and easily accessible catalysts has been one of the focuses in asymmetric phase-transfer catalysis. In this paper, a novel class of chiral bifunctional thiourea-ammonium phase-transfer catalysts were synthesized from commercially available alpha-amino acids. The structural modularity of these catalysts permits facile tunings to achieve optimum results, which was demonstrated in catalyzing the aza-Henry reaction with excellent enantioselectivities (up to 99.5% ee) and diastereoselectivities (up to >25:1 dr).

Discovery of N-Aroyl Diketone/Triketone Derivatives as Novel 4-Hydroxyphenylpyruvate Dioxygenase Inhibiting-Based Herbicides

4-Hydroxyphenylpyruvate dioxygenase (HPPD, EC 1.13.11.27) is an important target site for discovering new bleaching herbicides. To explore novel HPPD inhibitors with excellent herbicidal activity, a series of novel N-aroyl diketone/triketone derivatives were rationally designed by splicing active groups and bioisosterism. Bioassays revealed that most of these derivatives displayed preferable herbicidal activity against Echinochloa crus-galli (EC) at 0.045 mmol/m2 and Abutilon juncea (AJ) at 0.090 mmol/m2. In particular, compound I-f was more potent compared to the commercialized compound mesotrione. Molecular docking indicated that the corresponding active molecules of target compounds and mesotrione shared similar interplay with surrounding residues, which led to a perfect interaction with the active site of Arabidopsis thaliana HPPD.

Conglomerate formation and crystal structure of 4-phenyl-1,3-thiazolidin-2- one

Racemic 4-phenyl-1,3-thiazolidin-2-one (4-PTO) crystallizes in the form of conglomerate. The conglomerate formation has been confirmed by analyzing Weissenberg X-ray photographs and IR, Raman spectra of the racemate and the enantiopure 4-PTO crystals. The crystal structure of 4-PTO has been determined by X-ray diffraction, and the structural features are compared with those of other 4-phenyl-1,3-oxazolidin-2-one derivatives in order to understand the structural factors leading to the conglomerate formation. In 4-PTO crystals, the N-H?O intermolecular hydrogen bonds are formed between the amide groups of neighboring molecules in a homochiral zigzag chain. In addition, the intermolecular S?O close contacts are observed between the thioether and the carbonyl groups in the same chain unit. Moreover, the phenyl groups of homochiral 4-PTO molecules of different chain units take the T-shaped stacking orientation to each other due to the aromatic CH/pi interaction. These structural factors altogether reinforce the homochiral supramolecular assembly of chain structural units in the 4-PTO crystal.
