G Protein Coupled Receptors (GPCRs) perceive many extracellular signals and transduce them to heterotrimeric G proteins, which further transduce these signals intracellular to appropriate downstream effectors and thereby play an important role in various signaling pathways. G proteins are specialized proteins with the ability to bind the nucleotides guanosine triphosphate (GTP) and guanosine diphosphate (GDP). In unstimulated cells, the state of G alpha is defined by its interaction with GDP, G beta-gamma, and a GPCR. Upon receptor stimulation by a ligand, G alpha dissociates from the receptor and G beta-gamma, and GTP is exchanged for the bound GDP, which leads to G alpha activation. G alpha then goes on to activate other molecules in the cell. These effects include activating the MAPK and PI3K pathways, as well as inhibition of the Na+/H+ exchanger in the plasma membrane, and the lowering of intracellular Ca2+ levels.

Most human GPCRs can be grouped into five main families named; Glutamate, Rhodopsin, Adhesion, Frizzled/Taste2, and Secretin, forming the GRAFS classification system.

A series of studies showed that aberrant GPCR Signaling including those for GPCR-PCa, PSGR2, CaSR, GPR30, and GPR39 are associated with tumorigenesis or metastasis, thus interfering with these receptors and their downstream targets might provide an opportunity for the development of new strategies for cancer diagnosis, prevention and treatment. At present, modulators of GPCRs form a key area for the pharmaceutical industry, representing approximately 27% of all FDA-approved drugs.

Nicergoline

Nicergoline is an ergot derivative used to treat senile dementia and other disorders with vascular origins.Target: Alpha-1A adrenergic receptorNicergoline acts by inhibiting the postsynaptic alpha(1)-adrenoceptors on vascular smooth muscle. This inhibits the vasoconstrictor effect of circulating and locally released catecholamines (epinephrine and norepinephrine), resulting in peripheral vasodilation. Nicergoline displaced [3H]-prazosin bound to rat forebrain membranes pretreated with chloroethylclonidine (pKi = 9.9 +/- 0.2) at concentrations 60-fold lower than in rat liver membranes (pKi = 8.1 +/- 0.2). Finally, of the nicergoline metabolites studied, lumilysergol acted as a modest alpha 1 antagonist (bromonicotinic acid was devoid of alpha 1 antagonist activity). In conclusion, nicergoline is a potent and selective alpha 1A-adrenoceptor subtype antagonist, an alpha 1-adrenoceptor subtype which is mainly represented in resistance arteries [1].

Nebivolol hydrochloride selectively inhibits β1- adrenergic receptor with IC50 of 0.8 nM.Target: β1- adrenergic receptorNebivolol reduces cell proliferation of human coronary smooth muscle cells (haCSMCs) and endothelial cells (haECs) in a concentration- and time-dependent maner. Nebivolol treatment for 7 days causes significant reduction in cell growth of haCSMCs with IC50 of 6.1 μM, and inhibits accelerated haCSMC proliferation stimulated by growth factors PDGF-BB, bFGF, and TGFβ with IC50 values of 6.8 μM, 6.4 μM and 7.7 μM, repectively. Nebivolol treatment (10-5 M) of haCSMCs for 48 hours induces a moderate apoptosis of 23% and a decrease from 16% to 5% in the number of cells in S-phase. During Nebivolol incubation, NO formation of HaCEs increases, while endothelin-1 transcription and secretion are suppressed.Administratiion of Nebivolol (initially by iv within 10 minutes of reperfusion and then orally) to rats with myocardial infarction (MI) reduces myocardial apoptosis, which is mediated by regulation of NO . Nebivolol, significantly, prevents left ventricular (LV) pressure changes, reduces total and regional apoptotic cardiomyocytes. Nebivolol treatment lowers mean blood pressure (MBP) in rats with MI slightly, but not significantly.
