4-Methoxy-N-[2-(trifluoromethyl)biphenyl-4-ylcarbamoyl]nicotinamide: A Potent and Selective Agonist of S1P1
摘要:
The sphingosine-1-phosphate-1 receptor (S1P(1)) and its endogenous ligand sphingosine-1-phosphate (S1P) cooperatively regulate lymphocyte trafficking from the lymphatic system. Herein, we disclose 4-methoxy-N[2-(trifluoromethyl)biphenyl-4-ylcarbamoyl]nicotinamide (8), an uncommon example of a synthetic S1P(1) agonist lacking a polar headgroup, which is shown to effect dramatic reduction of circulating lymphocytes (POC = -78%) in rat 24 h after a single oral dose (1 mg/kg). The excellent potency that 8 exhibits toward S1P(1) (EC50 = 0.035 mu M, 96% efficacy) and the >100-fold selectivity that it displays against receptor subtypes S1P(2-5) suggest that it may serve as a valuable tool to understand the clinical relevance of selective S1P(1) agonism.

Methods and compositions for producing mature myotubes are provided herein. In some instances, the method involves contacting a myoblast in an in vitro culture with a compound, wherein the contacting the myoblast in the in vitro culture with the compound results in generation of mature myotubes or myotube-like cells. In some cases, methods of treatment are provided involving treating a subject with a compound such as a Chk1 inhibitor in order to treat muscle deficiency. The compound may be administered as a stand-alone therapy or in combination with a cell therapy, such as introduction of muscle precursor cells such as satellite cells or myoblasts. Methods for identifying compounds that induce formation of mature myotubes or myotube-like cells from myoblasts are also provided herein, as well as methods of using the identified compounds to treat subjects.
