KCN1 KCN1, a novel synthetic sulfonamide, is a HIF pathway inhibitor with potential anticancer activity in vitro and in vivo anti-pancreatic cancer activities and preclinical pharmacology. KCN1 specifically inhibited HIF reporter gene activity in several glioma cell lines at the nanomolar level. KCN1 also downregulated transcription of endogenous HIF-1 target genes, such as VEGF, Glut-1, and carbonic anhydrase 9, in a hypoxia-responsive element (HRE)-dependent manner. KCN1 potently inhibited the growth of subcutaneous malignant glioma tumor xenografts with minimal adverse effects on the host. Mechanistically, KCN1 did not downregulate the levels of HIF-1α or other components of the HIF transcriptional complex; rather, it antagonized hypoxia-inducible transcription by disrupting the interaction of HIF-1α with transcriptional coactivators p300/CBP.CONCLUSIONS: The new HIF pathway inhibitor KCN1 has antitumor activity in mouse models, supporting its further translation for the treatment of human tumors displaying hypoxia or HIF overexpression.

Keratin Keratin is a fibrous protein that comprises the majority of the structure of hair, nails, and the outer layer of the skin in mammals. It is a very strong and durable protein that provides essential mechanical strength and protective functions to these structures. In hair, keratin helps to give it its strength, flexibility, and elasticity. In nails, it provides the hardness and durability needed to protect them from damage. In the skin, it helps to form a barrier against harmful substances and pathogens. Keratin is produced by special cells called keratinocytes, which are found in the outer layer of the skin and in the hair follicles. Uses: 1. Hair Care Products: Keratin is widely used in...n strengthening weak and brittle nails, and promoting nail growth. 4. Medical Application: Keratin is used in the medical field for wound healing and tissue engineering. It acts as a bioactive material that promotes cell adhesion, proliferation, and differentiation, thereby accelerating the healing process. 5. Textile Industry: Keratin is used in the textile industry for manufacturing clothes and fabrics. It helps in providing a natural luster, strength, and durability to the fabrics, making them more resistant to wear and tear. Group: Hair Actives. CAS No. 68238-35-7. Product ID: ACM68238357. Appearance: Keratin is a fibrous protein that appears as long, slender, and cylindrical strands. Alfa Chemistry. 4
Keratinase, Recombinant Keratinase is a particular class of extracellular proteolytic inducible enzyme with the capability of degrading insoluble keratin substrates. It is important for hydrolyzing hair, feather, and collagen in sewage system during waste water treatment. It is also useful in food industry, animal feed preparation etc. Insoluble feather keratin from poultry industry may be converted by enzymatic hydrolysis to glues, feedstuffs, fertilizers, films or used for the production of rare amino acids serine, cysteine and proline. Applications: Keratinase was used for enzymatic treatment of elementary body (eb), gag molecules, and cells in the study of the role glycosaminoglycans (gags) in the invasion of host cells by chlamydia pneumoniae strains.

Keratin Protein, Hydrolyzed Sheep-wool derived, hydrolyzed alpha-keratin protein carefully monitored during its manufacture to ensure the lowest possible odor and a low ash. Keratin is a highly specialized fibrous protein, which is found in hair, feathers, wool and nails. Keratin is distinct from other proteins in that it is rich in cysteine (a sulfur-containing amino acid) giving keratin a unique strength and protective quality. Derived from sheep's wool. Contains 20-23% of protein. Molecular weight: 1,100-3,300 Da. Gluten-free. Uses: All kinds of hair care products including shampoos, hair conditioners, hair balms, hair pomades and also skin care products including lotions and creams.
