Abstract
Glycogen Synthase Kinase-3 (GSK-3) is a serine/threonine kinase with varied number of actions in cellular signalling systems making it an emerging target for diseases such as diabetes mellitus, cancer, chronic inflammation, bipolar affective disorders and Alzheimers disease. Various efforts have produced many potent small molecule inhibitors of GSK-3, which are being tested for modulation of glycogen metabolism, gene transcription, apoptosis and enhancement of insulin-stimulated glucose transport. Majority of the reported inhibitors show their inhibitory effects towards other phylogenetically related kinases also, like cyclin dependant kinases (CDKs). Thus it is important to develop inhibitors that can inhibit GSK-3 selectively. Rational approaches based on the knowledge of the receptor are best suited to address the selectivity problem. Several crystal structures of GSK-3β with different ligands are being reported. These are providing the necessary clues regarding the interaction in the ligand binding domain. Several molecular docking efforts are being taken up to identify the clues for enhancing selectivity towards GSK-3. In this review we present current efforts and future opportunities in designing selective GSK-3 inhibitors.

Nutrition and Metabolism in Musculoskeletal Diseases
The musculoskeletal system consists mainly of cartilage, bone, muscles, tendons, connective tissue and ligaments. Balanced metabolism is of vital importance for the homeostasis of the musculoskeletal system. A series of musculoskeletal diseases (for example, sarcopenia, osteoporosis) are resulted from the dysregulated metabolism of the musculoskeletal system. Furthermore, metabolic diseases (such ...read more
Protein Folding, Aggregation and Liquid-Liquid Phase Separation
Protein folding, misfolding and aggregation remain one of the main problems of interdisciplinary science not only because many questions are still open, but also because they are important from the point of view of practical application. Protein aggregation and formation of fibrillar structures, for example, is a hallmark of a ...read more
