Hitting Coronaviruses Where It Hurts: Antiviral Strategies Targeting Viral Proteins

open access: yesChemMedChem, Volume 21, Issue 19, 14 October 2026.
Viral proteins represent key vulnerabilities in human coronaviruses (HCoVs). This review outlines inhibitors targeting spike (S), main protease (Mpro), papain‐like protease (PLpro), and RNA‐dependent RNA polymerase (RdRp), mapping chemically diverse strategies that disrupt entry and replication, and provides an integrated view of current candidates ...

Optimization and validation of an RP-HPLC method for the estimation of 6-mercaptopurine in bulk and pharmaceutical formulations

open access: yesBrazilian Journal of Pharmaceutical Sciences, 2014
A reverse phase HPLC method is described for the determination of 6-mercaptopurine in bulk and tablets. Chromatography was carried on a C18 column using a mixture of acetonitrile and 0.05 mol/L sodium acetate buffer (10:90 v/v) as the mobile phase at a ...

Control of Gemcitabine Activity With Blue and Red Light

open access: yesChemistry – A European Journal, Volume 32, Issue 38, 13 October 2026.
Treating cancer with chemotherapy is generally associated with many side effects, which can be addressed by selectively releasing the desired drugs with visible light. Sixteen new blue light‐activatable cytostatics were introduced, with the gemcitabine derivative exhibiting ideal properties.

Demonstration of enzymatic activity converting azathioprine to 6-mercaptopurine [PDF]

open access: yes, 1978
The enzymatic conversion of azathioprine to 6-mercaptopurine was detected at pH 6.5 with rat liver supernatants, although the non-enzymatic reaction predominated at pH 7.0 and 7.5. Glutathione S-transferase may catalize this conversion. Activities of the

Arabinosyl-6-mercaptopurine and Arabinosyl-6-mercaptopurine-5'-phosphate: Comparison of Their Metabolic Effects

open access: yesExperimental Biology and Medicine, 1969
SummaryArabinosyl-6-mercaptopurine (Ara-6-MP), an effective inhibitor of the growth of the mouse tumors Ca755, Ehrlich and L1210, was incubated in fortified cellfree extracts of these tumor cells under conditions where 6-methylmercaptopurine riboside and inosine were converted to nucleotide. No nucleotide formation could be detected.

Genetic Polymorphism of Thiopurine S-Methyltransferase in Children with Acute Lymphoblastic Leukemia

open access: yesPakistan Journal of Medicine and Dentistry
Background: 6-Mercaptopurine (6-MP), a widely used anti-metabolite for the maintenance phase of childhood acute lymphoblastic leukemia (ALL), has been observed to cause myelotoxicity due to genetic polymorphism of thiopurine methyl transferase (TPMT ...
