EpoY (SD-142) is an irreversible inhibitor of the primary brain microtubule-associated tyrosine carboxypeptidase (TCP), a complex formed by vasohibin-1 (VASH1) and small vasohibin-binding protein (SVBP). By inhibiting TCP with an IC50 value of approximately 500 nM, EpoY effectively reduces the levels of detyrosinated α-tubulin, which is crucial for microtubule dynamics and neuronal differentiation. This inhibition results in significant differentiation defects and is linked to potential issues related to cancer and cardiomyopathy.

S-Adenosylhomocysteine (SAH) hydrolase is responsible for the reversible hydrolysis of SAH into adenosine and homocysteine. Inhibition of this enzyme leads to the accumulation of SAH within cells, thereby increasing the SAH to S-adenosylmethionine (SAM) ratio and subsequently inhibiting SAM-dependent methyltransferases. (−)-Neplanocin A, a potent and irreversible inhibitor of SAH hydrolase (Ki= 8.39 nM), exhibits significant antitumor activity against mouse leukemia L1210 cells and holds broad-spectrum antiviral properties. Its efficacy notably surpasses that of the reversible inhibitor 3-deazaneplanocin, especially in combating vesicular stomatitis, evidencing a higher potency with ID50 values of 0.07 μg/ml for Neplanocin A versus 0.3 μg/ml for 3-deazaneplanocin.
