NH2-PEG6-Val-Cit-PAB-OH is a cleavable ADC linker featuring a primary amine, a hydrophilic PEG spacer, a Val-Cit dipeptide, and a PAB group. The benzylic alcohol on the PAB can be used to attach with reactive groups such as PNP for conjugation with drug payloads. The primary amine is free to perform a wide variety of reactions such as coupling with carboxylic acids, reductive aminations with ketones or aldehydes, or other more specialized uses such as in SNAr reactions or heterocyclic chemistry. The Val-Cit dipeptide is cleaved by cellular proteases within the cell to allow for efficient payload delivery via an elimination mechanism within the PAB structure.

CAS No.: 3029090-15-8
N-Deschlorobenzoyl indomethacin-d3 is the deuterium labeled N-Deschlorobenzoyl indomethacin (HY-W008567). N-Deschlorobenzoyl indomethacin (Compound 18), the primary metabolite of indomethacin (HY-14397), lacks the N-p-chlorobenzoyl group in its structure. Consequently, N-Deschlorobenzoyl indomethacin loses inhibitory activity against AKR1C2 and AKR1C3 (AKR1C2 IC50 =100 μM, AKR1C3 IC50 >100 μM), exhibiting no selectivity .

Epigenetics refers to changes in phenotype that are not rooted in DNA sequence. Many types of epigenetic processes have been identified, including DNA methylation, alteration in the structure of histone proteins and gene regulation by small noncoding microRNAs. Modification of DNA, protein, or RNA, resulting in changes to the function and/or regulation of these molecules, without altering their primary sequences, reveals the complexities of cellular differentiation, embryology, the regulation of gene expression, aging, cancer, and other diseases.

MCE provide a unique collection of 2,031 epigenetics-related compounds that can be used in the research of the related diseases.

At the forefront of innovative drug discovery, every medicinal chemist faces the challenge of rapidly identifying high-quality hit compounds from vast repositories of chemical resources.

The MCE Natural Product Diversity Scaffold Library is the result of a streamlined optimization process built upon our existing natural product collection. Adhering to the rigorous selection principle of "retaining only one representative compound per BMS scaffold", we have concentrated the diversity of thousands of compounds into a high-value, low-redundancy core set containing 2,256 compounds. All compounds are derived from natural sources, inheriting their inherent advantages of structural complexity and drug-likeness. By eliminating redundancy, the library size is significantly reduced without any compromise to chemical diversity. This approach effectively lowers the cost and time required for primary screening while simplifying downstream data analysis and structure-activity relationship (SAR) studies.
