General description

EHNA is an adenosine deaminase inhibitor. It possesses antitumor action.

Application

EHNA hydrochloride has been used to treat microexplant culture to examine the direction and the motor responsible for the movement of autophagosomes in axons. It has also been used in nucleoside supplementation to inhibit the breakdown of deoxyadenosine by the enzyme adenosine deaminase.

Discover Bioactive Small Molecules for Cyclic Nucleotides

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.
