Multiple copies of the DHFR
gene havebeen found in tumor cells of some methotrexate-resistant patients, enabling the production of above-normal amounts of DHFR
QM/MM and Inverse Design for Novel Therapeutics Targeting Drug-Resistant pfDHFR-TS Malaria Shows how QM/MM calculations with the Inverse Design algorithm are used to develop mutation-resistance inhibitors, by designing ligands that are active against 3 known mutations from DHFR
from Plasmodium falciparum (malaria).
Now scientists working at Recipharm Biologics have also automated the Introgen OptiCHO DHFR
Similarly specific point mutations in the DHFR
gene are also known to be associated with pyremethamine resistance: alanine to valine at 16, asparagine to isoleucine at 51, cysteine to asparagine at 59, serine to asparagine or threonine at 108 and isoleucine to leucine at 164.
Because the DHFR
enzymatic assay may lack specificity and the radiochemical assay is time-consuming, there is a need for a more rapid and specific method that could be routinely applied to clinical practice.
The Company believes these biochemical features, together with preclinical and clinical data in a variety of tumors, suggest that pralatrexate may have a favorable safety and efficacy profile relative to methotrexate and other related DHFR
Through a discretionary allocation of 1 million core-hours at the Argonne Leadership Computing Facility (ALCF), researchers at Cloud Pharmaceuticals will use Mira, a 10-petaflops IBM Blue Gene/Q supercomputer to investigate inhibitors of the dihydrofolate reductase enzyme, or DHFR
, from multiple sources.
enzyme inhibition assay is a sensitive and specific method for determining MTX concentrations in biological fluids, but current assay methods are labor-intensive and time-consuming.
The Company believes these biochemical features, together with preclinical and clinical data in a variety of tumors, suggest that PDX may have a favorable safety and efficacy profile relative to methotrexate and other related DHFR
Pralatrexate is a novel, small molecule chemotherapeutic agent that inhibits dihydrofolate reductase, or DHFR
, a folic acid (folate)-dependent enzyme involved in the building of nucleic acid, or DNA, and other processes.
