Pyrrolidine, also known as tetrahydropyrrole, is a saturated five-membered heterocyclic ring, which is miscible with water. Pyrrolidine exists in many alkaloids and drug molecules, such as kappa opioids, antagonists of dopamine D4 receptors, and HIV reverse transcriptase inhibitors.
Bemcentinib is a potentially first-in-class selective AXL inhibitor in development for STK11 mutated NSCLC and severe respiratory infections. Extensive studies confirm the ability to combine bemcentinib with immune checkpoint inhibitors, chemotherapies and targeted therapies with the goal of improving a patient’s immune response and delaying the development of chemoresistance. Bemcentinib is currently being investigated in combination with immune checkpoint inhibition and chemotherapy in first line NSCLC patients harboring mutations in the STK11 gene, a known prognostic factor of poor response to existing therapies.
