Abstract:
Beta-ketoacyl-ACP utilizing enzymes in fatty acid, polyketide and acyl-homoserine lactone biosynthetic pathways are important targets for developing antimicrobial, anticancer and antiparasitic compounds. Published reports on successful isolation of beta-ketoacyl-ACPs in a laboratory remain scarce to date and thus most beta-ketoacyl-ACP utilizing enzymes are routinely characterized using small molecule substrates in lieu of the bonafide 3-oxoacyl-ACPs. We report the systematic investigation into the electronic, geometric and spatial aspects of beta-ketoacyl-chain recognition to develop 3-oxoacyl-ACP substrate mimics for two beta-ketoacyl-ACP utilizing quorum signal synthases.

TGF - β Signaling Pathway
Adrenergic Receptors: β Subtype
Isoprenaline > Adrenaline > Noradrenaline
Neurotransmitter binding to these receptors causes activation of adenylyl cyclase resulting in increased concentrations of cAMP and modulation of calcium ion channels within the cell. They are further classified into β1, β2, and β3 subtypes.

Antianginal Drugs: Nitrates and β-Blockers
Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow....
