Rifaximin, sold under the brand name Xifaxan among others, is a non-absorbable, broad-spectrum antibiotic mainly used to treat travelers' diarrhea. It is based on the rifamycin antibiotics family. Since its approval in Italy in 1987, it has been licensed in more than 30 countries for the treatment of a variety of non-infectius gastrointestinal ...
In the cancer disease state, the interaction of PD-L1 on the tumor cells with PD-1 on a T-cell reduces T-cell function signals to prevent the immune system from attacking the tumor cells. [9] Use of an inhibitor that blocks the interaction of PD-L1 with the PD-1 receptor can prevent the cancer from evading the immune system in this way. [9]

While odronextamab was on track to potentially become Regeneron's first blood cancer drug, it has a much smaller market opportunity of $200 million compared to other potential launches of the ...
A number of Rho kinase inhibitors are known. [15] [16] [17]Chemical structure of fasudil. AT-13148 [18]; BA-210; β-ElemeneBelumosudil; Chroman 1 [19] [20]; DJ4, which is a selective multi-specific ATP competitive inhibitor of activity of ROCK1 (IC50 of 5 nM), ROCK2 (IC50 of 50 nM), MRCKα (IC50 of 10 nM) and MRCKβ (IC50 of 100 nM) kinases without affecting activity of PAK1 and DMPK at 5 μM ...
The blocking antibody does not directly target tumor cells, but rather blocks the regulatory functions of CTLA-4, resulting in enhanced T-cell function. [4] Some new treatments hypothesize the blocking of PD-1, a programmed cell-death protein, which will result in longer-lived T-cells. The blocking antibody BMS-936559 has been shown to bind to ...
The rifamycin group includes the classic rifamycin drugs as well as the rifamycin derivatives rifampicin (or rifampin), rifabutin, rifapentine, rifalazil and rifaximin. Rifamycin, sold under the trade name Aemcolo, is approved in the United States for treatment of travelers' diarrhea in some circumstances. [1] [2] [3]
Antagonists will block the binding of an agonist at a receptor molecule, inhibiting the signal produced by a receptor–agonist coupling.. A receptor antagonist is a type of receptor ligand or drug that blocks or dampens a biological response by binding to and blocking a receptor rather than activating it like an agonist.
