RN-1 (hydrochloride) Usage And Synthesis

Uses

RN-1 Hydrochloride is a potent, irreversible inhibitor of LSD1. It blocks long-term but not short-term memory in mice following intraperitoneal administration. RN-1 also induces cytotoxicity in ovarian cancer cell lines and induces fetal hemoglobin synthesis while reducing disease pathology in sickle cell mice.

Biological Activity

rn-1 (hydrochloride) is a brain-penetrant, potent and irreversible lsd1 inhibitor with ic50 values of 10-70 nm [1].lysine-specific demethylase 1 (lsd1) is a flavin-dependent monoamine oxidase that demethylate mono- and di-methylated lysines, specifically histone 3, lysines 4 and 9 (h3k4 and h3k9) [2].rn-1 (hydrochloride) is a potent and irreversible lsd1 inhibitor with ic50 values of 10-70 nm. however, rn-1 is much less effective against mao-a and mao-b with ic50 values of 0.51 and 2.785 μm, respectively [1]. in ovarian cancer lines, rn-1 also induced cytotoxicity, which was correlated with the lsd1 inhibitory potential [3].following intraperitoneal administration in mice, rn-1 penetrated the blood-brain barrier and the brain/plasma exposure ratio was 88.9. in mice, rn-1 significantly impaired long-term memory but not short-term memory. and long-term memory impairment was due to a brain-specific effect [1]. in a sickle cell disease (scd) mouse model, rn-1 induced hbf synthesis and increased frequencies of hbf-positive cells and mature erythrocytes, as well as reduced reticulocytes and sickle cells. and the rn-1 treated mice did not exhibit the necrotic lesions in the liver and spleen [4].
