(+)-D-threo-PDMP is a ceramide analog and is one of the four possible stereoisomers of PDMP . (+)-D-threo-PDMP is an inhibitor of glucosylceramide synthase. It inhibits glucosylceramide synthase by 50% when used at a concentration of 5 μM in an enzyme assay. (+)-D-threo-PDMP is the active component of racemic DL-threo-PDMP .

D-threo-PPMP, a powerful glucosylceramide (GlcCer) synthase inhibitor, effectively impedes karyokinesis and decreases cyst formation.

Entacapone sodium salt inhibits catechol-O-methyltransferase(COMT) with similar IC50 in different tissues including live, duodenum, kidney and lung, but entacapone is more active than tolcapone in those tissues. Entacapone (< 100 μM) is a potent inhibitor of α-syn and β-amyloid (Aβ) oligomerization and fibrillogenesis, and also protects against extracellular toxicity induced by the aggregation of both proteins in PC12 cells.Entacapone sodium salt is a specific, potent, peripherally acting catechol-O-methyltransferase (COMT) inhibitor with IC50 of 151 nM for PD treatment.

L-778123 is an inhibitor of FPTase and GGPTase-I. The combination of L-778123 and radiotherapy at dose level 1 showed acceptable toxicity in patients with locally advanced pancreatic cancer.
