Biochem/physiol Actions

PQ-10 (6,7-dimethoxy-4-[3-(quinoxalin-2-yloxy)pyrrolidin-1-yl]quinazoline), is capable of suppressing tumor cell growth. It can also reverse the RO-4-1284-induced sedation and catalepsy.
PQ-10 is a potent and selective inhibitor of phosphodiesterase 10A (PDE10).
PQ-10 is a potent and selective inhibitor of phosphodiesterase 10A (PDE10). Apparently, PQ-10 enhances basic auditory information processing in rats. PQ-10 as other PED10 inhibitors suppresses a growth of human non-small cell lung cancer (NSCLC) cell lines.

Cyclic nucleotides, including cyclic AMP (cAMP), cyclic GMP (cGMP) and cyclic ADP-ribose, have been extensively studied as second messengers of intracellular events initiated by activation of GPCRs. cAMP modifies cell function in all eukaryotic cells, principally through the activation of cAMP-dependent protein kinase (PKA), but also through cAMP-gated ion channels and guanine nucleotide exchange factors directly activated by cAMP.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
