Product Data
Biological target:
NSC 185058 is an inhibitor of ATG4B, a major cysteine protease.
In vitro activity:
NSC185058 inhibited the C-terminal cleavage of LC3B by ATG4B in rapamycin-treated 293T cells and in amino acid starved HuH7 cells. Meanwhile, NSC377071 had a minimal effect on rapamycin-induced ATG4B activity in 293T cells as evidenced by LC3B cleavage, but inhibited starvation-induced activity in HuH7 cells. The results demonstrate that NSC185058 effectively inhibits ATG4B activity in vitro and in cells, but that NSC377071 is likely acting on a different target protein. NSC185058 was found to be cytotoxic to Saos-2 cells during a 48 h exposure (Fig. 8A). Reference: Autophagy. 2014;10(11):2021-35. https://pubmed.ncbi.nlm.nih.gov/25483883/
In vivo activity:
In vivo, NSC (NSC185058) and CQ significantly decreased M83 glioma xenograft growth in the flanks of mice (Figures S7C–S7E). NSC did not enhance the effects of STK26 knockout (KO) on M83 xenograft growth and autophagic activity in vivo (Figures S7F–S7I).

Note: There can be variations in solubility for the same chemical from different vendors or different batches from the same vendor. The following factors can affect the solubility of the same chemical: solvent used for crystallization, residual solvent content, polymorphism, salt versus free form, degree of hydration, solvent temperature. Please use the solubility data as a reference only. Warming and sonication will facilitate dissolving. Still have questions? Please contact our Technical Support scientists.
