Design, synthesis and anti-proliferative evaluation of new pyridine-2,3-dihydrothiazole/thiazolidin-4-one hybrids as dual CDK2/GSK3β kinase inhibitors.

Herein, the molecular hybridization drug discovery approach was used in the design and synthesis of twelve novel pyridine-2,3-dihydrothiazole hybrids (2a,b-5a,b and 13a,b-14a,b) and fourteen pyridine-thiazolidin-4-one hybrids (6a,b-12a,b) as anti-proliferative analogues targeting CDK2 and GSK3β kinase inhibition. Almost all of the newly synthesized hybrids, including their precursors (1a,b), were evaluated for their anti-proliferative activity against three human cancer cell lines-MCF-7, HepG2 and HEp-2-as well as normal Vero cell lines. Both compounds 1a (pyridine-thiourea precursor) and 8a (pyridine-5-acetyl-thiazolidin-4-one hybrid) exhibited excellent anti-proliferative activity against HEp-2 (IC = 7.

Co-administration of xylo-oligosaccharides produced by immobilized Aspergillus terreus xylanase with carbimazole to mitigate its adverse effects on the adrenal gland.

Carbimazole has disadvantages on different body organs, especially the thyroid gland and, rarely, the adrenal glands. Most studies have not suggested any solution or medication for ameliorating the noxious effects of drugs on the glands. Our study focused on the production of xylooligosaccharide (XOS), which, when coadministered with carbimazole, relieves the toxic effects of the drug on the adrenal glands.
