MedKoo CAT#: 205920

CAS#: 23261-20-3

Description: VAL-083 is a bi-functional alkylating agent, with potential antineoplastic activity. Upon administration, VAL-083 crosses the blood brain barrier (BBB) and appears to be selective for tumor cells. This agent alkylates and crosslinks DNA which ultimately leads to a reduction in cancer cell proliferation. In addition, VAL-083 does not show cross-resistance to other conventional chemotherapeutic agents and has a long half-life in the brain.

Biological target: VAL-083 is an alkylating agent that creates N7 methylation on DNA.
In vitro activity: In this study’s cohort, VAL-083 was significantly more effective than TMZ (Fig. 6a, b) and the response was not dependent on MGMT promoter methylation status (Fig. 6c). The response was similar in treatment-naïve and relapsed organoids (Supplementary Fig. 6c, online resource), suggesting that VAL-083 is able to overcome TMZ resistance. Reference: Acta Neuropathol. 2020; 140(6): 919–949. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7666297/
In vivo activity: VAL-083 monotherapy led to a dramatic reduction in tumor growth (Fig. 6e), an effect which was only mildly accentuated by combined treatment. Histological assessment of tumor-containing mouse brains confirmed the strong reduction in tumor volume upon VAL-083 treatment (Supplementary Fig. 6e, online resource). This was paralleled by an increase in DNA damage in tumor cells, determined by H2AX phosphorylation (H2AX-P) (Supplementary Fig. 6f, online resource). Limited H2AX-P was also seen in normal brain cells close to the meninges and the subventricular zone, but to a much lower extent than in tumor cells. In summary, this study shows that VAL-083 has a consistently favorable drug profile against GBM; thus, representing a promising candidate for GBM treatment either alone or in combination with antiangiogenic compounds.
