GSK-LSD1 dihydrochloride (GSK-LSD1 2HCl) is a specificity irreversible LSD1 inhibitor (IC50: 16 nM). The selectivity of GSK-LSD1 for LSD1 is >1000 fold over other closely related FAD utilizing enzymes (i.e. MAO-A, LSD2, MAO-B).

AS8351 (NSC51355) is a histone demethylase inhibitor. It has been used in combination with CHIR99021, A 83-01, BIX01294, SC-1, Y-27632, OAC2, SU 16f, and JNJ-10198409 to induce reprogramming of human fetal lung fibroblasts into functional cardiomyocytes.

Zavondemstat (QC8222 free base) is a histone lysine demethylase 4 (KDM4) inhibitor with anticancer and antitumor activity for the study of triple-negative and breast cancers.

Procaine hydrochloride (Novocaine HCl) is the hydrochloride salt form of procaine, a benzoic acid derivative with local anesthetic and antiarrhythmic properties. Procaine binds to and inhibits voltage-gated sodiumchannels, thereby inhibiting the ionic flux required for the initiation and conduction of impulses. In addition, this agent increases electrical excitation threshold, reduces rate of rise of action potential and slows nerve impulse propagation thereby causing loss of sensation.

FY-21 is a selective LSD1 inhibitor (IC50= 340 nM) that inhibits proliferation and colony formation of leukemia cells, decreases mRNA levels of the transcription factors HOXA9 and MEIS1, and can be used in the study of leukemia.
