Therapeutic potential inhibitor for dipeptidyl peptidase IV in diabetic type 2: in silico approaches.

Diabetes mellitus (DM) is a metabolic disease marked by an excessive rise in blood sugar (glucose) levels caused by a partial or total absence of insulin production, combined with alterations in the metabolism of proteins, lipids, and carbohydrates. The International Diabetes Federation estimates that 425 million individuals globally had diabetes in 2017 which will be 629 million by 2045. Several medications are used to treat DM, but they have limitations and side effects including weight gain, nausea, vomiting, and damage to blood vessels and kidneys.

Exploration of leads from bis-indole based triazine derivatives targeting human aldose reductase in diabetic type 2: in-silico approaches.

Diabetes mellitus (DM) poses a major global healthcare challenge, highlighting the need for new treatments beyond current options. Currently available drugs have side effects including weight gain, nausea, vomiting, diarrhea, insulin resistance etc. Therefore, given the benefits of indole derivatives in diabetes and the lack of computational studies on bis-indole-based triazine derivatives with aldose reductase (AR), this study employs in-silico analysis to explore their potential as type-2 diabetes treatments.

Virtual screening of pyrazole derivatives of usnic acid as new class of anti-hyperglycemic agents against PPARγ agonists.

Unlabelled: The finest sources of therapeutic agents are natural products, and usnic acid is a secondary metabolite derived from lichen that has a wide range of biological actions, including anti-viral, anti-cancer, anti-bacterial, and anti-diabetic (hyperglycemia).

Inside the cracked kernel: establishing the molecular basis of AMG510 and MRTX849 in destabilising KRASG12C mutant switch I and II in cancer treatment.

The Kirsten rat sarcoma oncoprotein (KRAS) has been punctuated by drug development failures for decades due to frequent mutations that occur mostly at codon 12 and the seemingly intractable targeting of the protein. However, with advances in covalent targeting, the oncoprotein is being expunged from the 'undruggable' list of proteins. This feat has seen some covalent drugs at different stages of clinical trials.

Prioritizing the Catalytic Gatekeepers through Pan- Inhibitory Mechanism of Entrectinib against ALK, ROS1 and TRKA Tyrosine Kinases.

Despite the remarkable clinical activity of kinase inhibitors against anaplastic lymphoma kinase (ALK) and the closely related Ros1 and TRKA kinases, the emergence of resistance to these inhibitors often leads to relapse in most patients. Resistance is usually in the form of mutations and brain metastasis or inhibitors failing to penetrate the blood-brain barrier. The discovery of entrectinib has recently paved way for further exploration of kinase inhibitors that target ALK after it has reportedly demonstrated potency against ALK, Ros1, and TRKA kinases.
