PD-1 and PD-L1 inhibitors act to inhibit the association of the programmed death-ligand 1 with its receptor, programmed cell death protein 1 (PD-1). The interaction of these cell surface proteins is involved in the suppression of the immune system and occurs following infection to limit the killing of bystander host cells and prevent autoimmune ...

Umbralisib (trade name Ukoniq; codenamed TGR-1202, Rp-5264; PIK3CD and casein kinase CSNK1E inhibitor): FDA-approved in February 2021 for treatment of relapsed or refractory marginal zone lymphoma (MZL) after at least one prior anti-CD20-based regimen, and treatment of relapsed or refractory follicular lymphoma after at least three prior lines ...
Index inducer or just inducer predictably induce metabolism via a given pathway and are commonly used in prospective clinical drug-drug interaction studies. [2]Strong, moderate, and weak inducers are drugs that decreases the AUC of sensitive index substrates of a given metabolic pathway by ≥80%, ≥50% to <80%, and ≥20% to <50%, respectively.
In contrast to irreversible inhibitors, reversible inhibitors generally do not undergo chemical reactions when bound to the enzyme and can be easily removed by dilution or dialysis. A special case is covalent reversible inhibitors that form a chemical bond with the enzyme, but the bond can be cleaved so the inhibition is fully reversible.
The discovery of the Wee1 gene is accredited to Paul Nurse, who first identified it in fission yeast (Schizosaccharomyces pombe) in 1978. In his initial experiments, Nurse demonstrated Wee1 to be a negative regulator of mitosis, such that Wee1+ activity was critical in preventing premature mitosis in Cdc25+ (a mitotic inducer) yeast cells and increased Wee1+ expression could further delay cell ...
[21] [26] In the case of proton pump inhibitors, PMs exhibit a drug exposure that is 3 to 13 times higher than that of EMs. [27] Loss-of-function alleles, CYP2C19*2 and CYP2C19*3 (and others, which are the subject of ongoing research) predict PMs, [21] and the gain-of-function CYP2C19*17 allele predicts UMs. [24]
Histone deacetylase 6 is an enzyme that in humans is encoded by the HDAC6 gene. [ 5 ] [ 6 ] HDAC6 has emerged as a highly promising candidate to selectively inhibit as a therapeutic strategy to combat several types of cancer and neurodegenerative disorders.
