RMC-4745 can be used for the study of breast cancer.

L-Glutamine GMP is L-Glutamine (HY-N0390) produced by using GMP guidelines. GMP small molecules works appropriately as an auxiliary reagent for cell therapy manufacture. L-Glutamine is an orally active nutritional agent and cellular metabolism regulator. L-Glutamine is taken up in a Na⁺-dependent manner and targets multiple key molecules including glutaminase, mTORC1, NF-κB, STAT-3 and HIF-1α. L-Glutamine enhances glutaminolytic catabolism, drives the conversion of glutamate to α-ketoglutarate, thereby regulating gene expression, integrating metabolic signals, mediating glutamine flux and maintaining redox homeostasis. L-Glutamine also promotes cell proliferation, osteogenic differentiation and fracture healing, exerts neuroprotective and cardioprotective effects, and inhibits osteoarthritis. L-Glutamine can be applied to research related to osteoporosis, osteoarthritis, ischemic stroke and acute cantharidin-induced cardiotoxicity.
