Pentigetide is a sythsis pepetide (Asp-Ser-Asp-Pro-Arg or D-S-D-P-R), also know as “HEPP” for “Human IgE Pentapeptide”. Pentigetide can not produce IgE inhibition in several different systems, due to the aspartic acids in HEPP changed into an asparagine.

C 87 is a small-molecule TNF-α inhibitor. C 87 directly binds to TNFα, potently inhibits TNF-α-induced cytotoxicity (IC50 = 8.73 μM), and effectively blocks TNF-α-triggered signaling activities.

Delsoline is not only effective in preventing ventricular fibrillation and arrythmia, but can raise the intebsity of the threthold of electrical shocks to cause ventricular fibrillation in rabbits.
