Vitamin K5

Vitamin K5 (Synkamin), a photosensitizer and antimicrobial agent, serves as a specific PKM2 inhibitor, demonstrating IC 50 values of 28, 191, and 120 μM against PKM2, PKM1, and PKL, respectively. It induces apoptosis in colon 26 cells and is utilized in infection and cancer research. Additionally, Vitamin K5 finds application as a preservative in pharmaceuticals, foods, and beverages [1] [2] [3].

5-Dehydroxyparatocarpin K is a natural product of Psoralea, Fabaceae. The catalog number is TN3105 and the CAS number is 124858-37-3. 5-Dehydroxyparatocarpin K can be used as a reference standard.

Vitamin K (Kephton) has blood coagulation action and is important for coagulation factors, matrix-Gla protein, and osteocalcin.

K-Ras ligand-Linker Conjugate 5 is a chemical compound that combines a ligand for the K-Ras recruiting moiety with a PROTAC linker. This linker is responsible for recruiting E3 ligases such as VHL, CRBN, MDM2, and IAP. The K-Ras ligand-Linker Conjugate 5 plays a crucial role in the synthesis of PROTAC K-Ras Degrader-1, a highly potent K-Ras degrader. In SW1573 cells, this degrader exhibits an impressive degradation efficacy of ≥70% [1].
