synovex one grass Prokineticins are angiogenic hormones that activate two G protein-coupled receptors: PKR1 and PKR2.PKR1 has emerged as a critical mediator of cardiovascular homeostasis and cardioprotection.Identification of non-peptide PKR1 agonists that contribute to myocardial repair and collateral vessel growth hold promises for treatment of h
Abstract In this research, a simple, efficient and novel protocol is eveloped for the direct synthesis of symmetrical disulfides here using dipotassium 1,3,4-thiadiazole-2,5-bis(thiolate) as a new, low toxicity, inexpensive, stable solid and free of foul-smelling thiols for synthesize symmetric diaryl/dialkyl disulfides from aryl and alkyl halides
