Purity:  99.82%
1,7-Dimethyluric acid is an N-methylated uric acid and purine derivative, as well as a caffeine metabolite. When 1,7-Dimethyluric acid is acted upon by peroxidase in the presence of H2O2, it follows the same oxidation pathway to generate a UV-absorbing intermediate, which decays via first-order kinetics. 1,7-Dimethyluric acid can adsorb onto pyrolytic graphite electrodes, but not onto glassy carbon electrodes or platinum electrodes. The N-methylation modification of its pyrimidine ring prevents ring contraction of the diol intermediate, and no NMR evidence of O-alkylation is observed during propylation under the test conditions .

19F-NMR has proved to be a detection mode in fragment-based drug discovery (FBDD) for studies of protein structure and interactions. 19F shows high sensitivity for NMR detection, and the exquisite sensitivity of 19F chemical shifts and linewidths to ligand binding all make it a valuable approach in FBDD.F (Fluorine) -Fragments can be used for 19F-NMR detection after binding to target proteins, and can be used as an effective 19F-NMR tool for FBDD.

MCE designs a unique collection of 5,077 F-fragments, all of which obey a heuristic rule called the “Rule of Three (RO3)”, in which molecular weight ≤300 Da, the number of hydrogen bond donors (H-donors) ≤3, the number of hydrogen bond acceptors (H-acceptors) is ≤3 and cLogP is ≤3. This F-fragments library is an important source of lead-like drugs.
