72730-39-3 Usage

General Description

2-Mercapto-1,3-benzoxazole-5-carboxylic acid methyl ester is a chemical compound with a molecular formula C10H7NO3S and a molar mass of 217.23 g/mol. It is a derivative of benzoxazole, which is a heterocyclic compound containing both benzene and oxazole rings. This chemical is commonly used as a building block for the synthesis of organic compounds and pharmaceuticals. It is known for its thiol or mercapto group, which makes it useful for various chemical reactions and industrial applications. Additionally, the carboxylic acid and methyl ester groups provide versatility in terms of chemical reactivity and solubility in organic solvents.

Check Digit Verification of cas no

The CAS Registry Mumber 72730-39-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,7,3 and 0 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 72730-39:
(7*7)+(6*2)+(5*7)+(4*3)+(3*0)+(2*3)+(1*9)=123
123 % 10 = 3
So 72730-39-3 is a valid CAS Registry Number.

Tunable Amine-Reactive Electrophiles for Selective Profiling of Lysine

Proteome profiling by activated esters identified >9000 ligandable lysines but they are limited as covalent inhibitors due to poor hydrolytic stability. Here we report our efforts to design and discover a new series of tunable amine-reactive electrophiles (TAREs) for selective and robust labeling of lysine. The major challenges in developing selective probes for lysine are the high nucleophilicity of cysteines and poor hydrolytic stability. Our work circumvents these challenges by a unique design of the TAREs that form stable adducts with lysine and on reaction with cysteine generate another reactive electrophiles for lysine. We highlight that TAREs exhibit substantially high hydrolytic stability as compared to the activated esters and are non-cytotoxic thus have the potential to act as covalent ligands. We applied these alternative TAREs for the intracellular labeling of proteins in different cell lines, and for the selective identification of lysines in the human proteome on a global scale.

Paragraph 00920; 002498-002500, (2021/01/23)

The present invention provides compounds, compositions thereof, and methods of using the same. The compounds include an IRAK binding moiety capable of binding to IRAK4 and a degradation inducing moiety (DIM). The DIM could be DTM a ligase binding moiety (LBM) or lysine mimetic. The compounds could be useful as IRAK protein kinase inhibitors and applied to IRAK mediated disorders.

Design, synthesis and pharmacology of aortic-selective acyl-CoA: Cholesterol O-acyltransferase (ACAT/SOAT) inhibitors

We describe our molecular design of aortic-selective acyl-coenzyme A:cholesterol O-acyltransferase (ACAT, also abbreviated as SOAT) inhibitors, their structure–activity relationships (SARs) and their pharmacokinetic (PK) and pharmacological profiles. The connection of two weak ligands—N-(2,6-diisopropylphenyl)acetamide (50% inhibitory concentration [IC50] = 8.6 μM) and 2-(methylthio)benzo[d]oxazole (IC50 = 31 μM)—via a linker comprising a 6 methylene group chains yielded a highly potent molecule, 9-(benzo[d]oxazol-2-ylthio)-N-(2,6-diisopropylphenyl)nonanamide (3h) that exhibited high potency (IC50 = 0.004 μM) toward aortic ACAT. This head-to-tail design made it possible to markedly enhance the activity to 2150- to 7750-fold and to discriminate the isoform-selectivity based on the double-induced fit mechanism. At doses of 1 and 3 mg/kg, 3h significantly decreased the lipid-accumulation areas in the aortic arch to 74 and 69%, respectively without reducing the plasma total cholesterol level in high fat- and cholesterol-fed F1B hamsters. Here, we demonstrate the antiatherosclerotic effect of 3h in vivo via its direct action on aortic ACAT and its powerful modulator of cholesterol level. This molecule is a potential therapeutic agent for the treatment of diseases involving ACAT-1 overexpression.
