Pharmacodynamics

SF1126 is a covalent conjugate of LY294002 that contains a peptide-based targeting group to help increase the localization of the drug in the neovascular component supporting tumor growth. SF1126 is a highly water soluble solid which aids its administration via i.v. or s.c. injections. In vivo it converts spontaneously at physiological pH to LY294002 in a way that is well tolerated in mice, rats, and dogs. SF1126 has been evaluated in numerous animal tumor models showing good tumor inhibition or tumor regression.

Mechanism of action

SF1126 is a small molecule conjugate containing a pan-PI3K inhibitor that selectively inhibits all PI3K class IA isoforms and other key members of the PI3K superfamily, including DNA-PK and mTOR. A major factor in tumor resistance to approved chemotherapy agents is thought to be the activation of the PI3K/PTEN pathway. As a result, it is thought that inhibiting this pathway, via SF1126, could cause the resetting of sensitivity to approved agents and exhibit synergistic anticancer effects.
