Val-Ala-PABC-Exatecan trifluoroacetate (Cat No.: I040181) is a targeted drug conjugate composed of the chemotherapy agent Exatecan linked to a peptide sequence (Val-Ala) via a cleavable PABC linker. This conjugate allows for selective delivery of Exatecan to cancer cells, enhancing the drug’s efficacy while minimizing systemic toxicity. The trifluoroacetate salt form aids in stability and solubility, supporting its potential in cancer treatment by improving the precision and potency of chemotherapy. It’s primarily studied for its applications in oncology.
