(2S)-2-Amino-4-(butylsulfonimidoyl)butanoic acid (BD136012) is a building block containing a sulfoximine group. Several CDK and ATR inhibitors have exemplified the utilization of the NH sulfoximine group as abioisostere for a sulfonamide group to overcome the main project hurdles of aqueous solubility, sulfonamide-mediated off-target activity and IP. Moreover, its NH group could be expediently further functionalized through Buchwald-Hartwig coupling reaction and multifarious nucleophilic reactions.. Recommended Products is: 4381-25-3 and 1621962-30-8.
Approx. 20-30% of human lung adenocarcinomas (LUADs) harbor mutations in Kelch-like ECH-associated protein 1 (KEAP1) that hyperactivate the nuclear factor, erythroid 2-like 2 (NFE2L2) antioxidant program. We previously showed that Kras-driven Keap1-mutant LUAD is highly aggressive and dependent on glutaminolysis. Here we performed a druggable genome CRISPR screen and uncovered a Keap1-mutant-specific dependency on solute carrier family 33 member 1 (Slc33a1), as well as several functionally related genes associated with the unfolded protein response. Genetic and biochem. experiments using mouse and human Keap1-mutant tumor lines, as well as preclin. genetically engineered mouse models, validate Slc33a1 as a robust Keap1-mutant-specific dependency. Furthermore, unbiased genome-wide CRISPR screening identified addnl. genes related to Slc33a1 dependency. Overall, our study provides a rationale for stratification of patients harboring KEAP1-mutant or NRF2-hyperactivated tumors as likely responders to targeted SLC33A1 inhibition and underscores the value of integrating functional genetic approaches with genetically engineered mouse models to identify and validate genotype-specific therapeutic targets.
Keap1 mutation renders lung adenocarcinomas dependent on Slc33a1. Recommended basis is Sulfoximine, Bioisosteric. Products is: https://www.ambeed.com/products/50578-18-2.html, 145026-07-9
