Quality Control & Documentation
Biological Activity

SEC inhibitor KL-1 (KL-1) is a potent and selective inhibitor of super elongation complex (SEC) that disrupts the interaction between the SEC scaffolding protein AFF4 and P-TEFb, resulting in impaired release of Pol II from promoter-proximal pause sites and a reduced average rate of processive transcription elongation. KL-1 exhibits an dose-dependent inhibitory effect on AFF4-CCNT1 interaction with Ki of 3.48 μM.

7-Deoxyloganin

7-Deoxyloganin is a biosynthetic precursor of Loganin. 7-Deoxyloganin undergoes hydroxylation catalyzed by 7-deoxyloganin 7-hydroxylase, a cytochrome P450-dependent monooxygenase, to produce Loganin.

Mannose-BSA

Mannose-BSA is an important organic intermediate that combines the properties of mannose and bovine serum albumin, which is of unique value in the field of scientific research, and can be used as a key substance in a variety of organic synthesis reactions. Mannose is an important monosaccharide that binds specifically to mannose receptors (e.g., CD206 receptors on dendritic cells and macrophages), and therefore has a wide range of applications in immunomodulation and targeted drug delivery. BSA is a protein carrier that is commonly used for biocoupling, and its abundant surface amino groups can covalently bind to mannose to form a mannose-BSA complex.

O-acetylcamptothecin

O-acetylcamptothecin is a derivative of camptothecin, a naturally occurring alkaloid extracted from the bark of the Chinese tree Camptotheca acuminata. Camptothecin and its derivatives are primarily known for their potent anticancer properties, particularly through their action as inhibitors of topoisomerase I, an enzyme critical for DNA replication and transcription.
