Pancreatic Lipase (PL) is a key enzyme responsible for the digestion of 50%–70% of dietary triglycerides, hence its inhibition is considered as a viable approach for the management of obesity. A series of indole-TZD hybrid analogues were synthesized, characterized and evaluated for their PL inhibitory activity. Knoevenagel condensation of various substituted indole-3-carboxaldehyde with substituted thiazolidinediones resulted in the formation of titled analogues. Analogues 6d and 6e exerted potent PL inhibitory activity (IC50-6.19 and 8.96?μM, respectively). Further, these analogues exerted a competitive mode of PL inhibition. Moreover, molecular modelling studies were in agreement with the in vitro results (Pearson's r?=.8682, p?.05). The fluorescence spectroscopic analysis further supported the strong binding affinity of these analogues with PL. A molecular dynamics study (20?ns) indicated that these analogues were stable in a dynamic environment. Thus, the present study highlighted the potential role of indole-thiazolidinedione hybrid analogues as potential PL inhibitors and further optimization might result in the development of new PL inhibitory lead candidates.

Mitochondrial demise is a key feature of progressive neuronal death contributing to acute and chronic neurological disorders. Recent studies identified a pivotal role for the BH3-only protein B-cell lymphoma-2 interacting domain death antagonist (Bid) for such mitochondrial damage and delayed neuronal death after oxygen-glucose deprivation, glutamate-induced excitotoxicity, or oxidative stress in vitro and after cerebral ischemia in vivo. Therefore, we developed new N-phenyl-substituted thiazolidine-2,4-dione derivatives as potent inhibitors of Bid-dependent neurotoxicity. The new compounds 6, 7, and 16 were identified as highly protective by extensive screening in a model of glutamate toxicity in immortalized mouse hippocampal neurons (HT-22 cells). These compounds significantly prevent truncated Bid-induced toxicity in the neuronal cell line, providing strong evidence that inhibition of Bid was the underlying mechanism of the observed protective effects. Furthermore, Bid-dependent hallmarks of mitochondrial dysfunction, such as loss of mitochondrial membrane potential, ATP depletion, as well as impairments in mitochondrial respiration, are significantly prevented by compounds 6, 7, and 16. Therefore, the present study identifies a class of N-phenyl thiazolidinediones as novel Bid-inhibiting neuroprotective agents that provide promising therapeutic perspectives for neurodegenerative diseases, in which Bid-mediated mitochondrial damage and associated intrinsic death pathways contribute to the underlying progressive loss of neurons.

Several thiosemicarbazones (7 and 8), 1,3-thiazolidin-4-ones (9, 10, 13, 14) and 2-thioxo-1,3-imidazolidin-4-ones (11) have been prepared starting from 8-bromo-7-hydroxy-5-methoxy-2-methyl-4-oxo-4H-1-benzopyran-6-carbaldehyde (3) and its 4-thio analogue (4). The anticonvulsant activity of all of the synthesized compounds was evaluated against maximal electrical shock (MES) and subcutaneous pentylenetetrazole (scPTZ) induced seizures. The neurotoxicity was assessed using the rota-rod test. Some of the tested compounds displayed potent anticonvulsant activity in the scPTZ test. ECV Editio Cantor Verlag.

The reaction of ethyl 5-phenylthioureido-3H-imidazole-4-carboxylate with bromoacetic acid afforded (imidazolylimino)thiazolidinones, which were transformed into the corresponding 5-arylidene-4-thiazolidinones by the reactions with aldehydes. Under the conditions of the Knoevenagel reaction, the thiazolidine ring in derivatives of 4-(4-oxothiazolidin-2-ylidene-amino)-3H- imidazole-4-carboxamides was opened to form substituted guanidines.
