CB-839 is the most advanced GLS1 inhibitor currently in clinical practice and has been shown to effectively inhibit tumor proliferation (102)

Inositol-derived molecules (sometimes referred to as inositol phosphoglycans) appear to act as secondary messengers in insulin pathways, helping cells respond more effectively to insulins signal.15 21 In human trials, MI supplementation has been associated with improvements in insulin sensitivity, fasting glucose, and postprandial glucose handling in certain populations including people with insulin resistance and pregnant individuals at risk of gestational diabetes.7 22 23 Meta-analyses suggest a reduction in gestational diabetes incidence when inositol is used preventively, though authors consistently note the need for larger, higher-quality randomized trials before firm clinical recommendations can be made.9 24 25 26 Ovarian function and hormone signaling In ovarian tissue, MI plays a role in follicle-stimulating hormone (FSH) signaling and oocyte maturation.27 28 DCI, meanwhile, appears more involved in insulin-mediated androgen production.29 Because these roles differ, some researchers propose that the balance between MI and DCI may matter, particularly in polycystic ovary syndrome (PCOS).30 Clinical trials in people with PCOS have reported improvements in ovulation frequency, menstrual regularity, and some metabolic markers with inositol supplementation.2 31 However, systematic reviews emphasize that many studies are small, heterogeneous, and of variable quality, and that more rigorous trials are needed before drawing strong conclusions.3 17 Body weight and cardiometabolic markers Beyond glucose control, inositol has been studied for broader metabolic effects
