JRN73958
JRN73958 (Reduced scytonemin) is a PI3K/Akt, MAPK, and NF-κB inhibitor found in Nostoc commune. JRN73958 inhibits nitric oxide production, induce reactive oxygen species (ROS) generation, and lead to autophagy. JRN73958 decreases LPS (HY-D1056)/IFNγ-induced PI3K/Akt, MAPK, and NF-κB activity. JRN73958 can be used for the research of leukemia.

Biological Activity
JRN73958 (0.5-2.5 μM; 2 h pretreatment) suppresses LPS/IFNγ-induced NO production in murine macrophage RAW264 cells in a concentration-dependent manner, with the strongest inhibition observed at 2.5 μM[1].
JRN73958 (2.5 μM; 2 h pretreatment) significantly reduces LPS/IFNγ-induced iNOS and COX-2 mRNA and protein expression in murine macrophage RAW264 cells[1].
JRN73958 (2.5 μM; 2 h pretreatment) inhibits LPS/IFNγ-mediated activation of p38 MAPK, ERK, SAPK/JNK, IκB, and STAT1 in murine macrophage RAW264 cells[1].
JRN73958 (2.5 μM; 2 h pretreatment) increases HO-1 expression 3.5-fold in murine macrophage RAW264 cells, and this induction is required for JRN73958's inhibitory effect on LPS/IFNγ-induced NO production[1].
JRN73958 (2.5 μM; 15-120 min) transiently increases intracellular ROS levels in murine macrophage RAW264 cells, reaching a 1.8-fold peak at 30 min[1].
JRN73958 (2.5 μM; 24 h) activates Nrf2/ARE signaling in murine macrophage RAW264 cells, increasing ARE enhancer activity to 1.35-fold relative to untreated cells[1].
JRN73958 (2.5 μM; 2 h) has its induced HO-1 expression in murine macrophage RAW264 cells suppressed by pretreatment with the antioxidant NAC or the kinase inhibitors SB203580 and LY294002[1].
JRN73958 (2.5 μM; 5-120 min pretreatment) activates p38 MAPK and PI3K/Akt signaling in murine macrophage RAW264 cells, with peak phosphorylation observed at 30 min[1].
JRN73958 (1.0-5.0 μM; 24-72 h) inhibits the growth of human T-lymphoid Jurkat cells with an IC50 of 1.8 μM[2].

JRN73958 (2.5 μM; 12 h) induces colocalization of LC3 and lysosomes, marking autophagosome/autolysosome formation, in human T-lymphoid Jurkat cells after 12 h of treatment[2].
JRN73958 (2.5 μM; 48 h) induces autophagic cell growth inhibition in human T-lymphoid Jurkat cells after 48 h of treatment, which is reversible by the autophagy inhibitor 3-MA[2].
