Biochem/physiol Actions

EHT 1864 inhibits Rac function. It prevents Aβ40 and Aβ42 production in vitro without direct inhibition of g-secretase.
EHT 1864 induces dissociation of bound nucleotides. EHT 1864 induced inhibition of Rac prevents its association with downstream effectors. It is known to prevent estrogen-induced tumor cell proliferation in breast cancer.

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.
