Article Abstract

The zoonosis caused by is increasing seriously. But commonly used antibiotic drugs often lead to resistance. dUTPase (dUTPase) plays a key role in the proliferation of , and was regarded as a potent drug target. However, there was little report about the dUTPase inhibitors. In this study, we discovered a series of novel dUTPase inhibitors to fight against . The first crystal structure of dUTPase was released, and a structure-based computational design was performed. Compounds and exhibited promising activities towards dUTPase (IC = 0.99 μM and 0.7 μM). In addition, they showed satisfied anti- activity (MIC value ranges from 0.5 to 2 mg/L) and low cytotoxicity, which were better than approved drugs oxytetracycline and florfenicol. Molecular modelling study indicated that hydrophobic interaction might be the main contribution for ligand binding. Our results suggested that dUTPase inhibitors might be a useful way to repress .

It has been demonstrated recently that knockout of the dUTPase enzyme leads to early embryonic lethality in mice. However, to explore the physiological processes arising upon the lack of dUTPase an effective and selective enzyme inhibitor is much needed. A highly specific and strong binding proteinaceous human dUTPase inhibitor described by us recently was a promising starting point to develop a molecular tool to study temporal and conditional dUTPase inhibition in cellulo.

Article Synopsis
  • Zoonotic infections are on the rise, but commonly used antibiotics are leading to resistance, highlighting the need for new treatment strategies.
  • The study identifies novel inhibitors of dUTPase, an important enzyme for pathogen proliferation, with promising effectiveness against the target organism and lower toxicity than existing antibiotics.
  • Molecular modeling suggests that hydrophobic interactions are key to how these inhibitors bind to dUTPase, indicating a potential new avenue for developing treatments against zoonosis.

Background: Shyonaka (Oroxylum indicum Vent) is widely used in Ayurveda and in ethnomedical practice for the treatment of inflammation, pain, diarrhea, non-healing ulcers, and cancer. Owing to the high prevalence of Epstein-Barr virus (EBV) infection in Nasopharyngeal carcinoma (NPC) patients, simultaneous targeting of proteins involved in both EBV replication and NPC proliferation might help to manage the disease effectively.

Objectives: This study is designed to identify potential dual targeting inhibitors from Oroxylum indicum having the potential to inhibit both EBV and NPC.

Recent studies in colorectal cancer patients (CRC) have shown that increased resistance to thymidylate synthase (TS) inhibitors such as 5-fluorouracil (5-FU), reduce the efficacy of standard of care (SoC) treatment regimens. The nucleotide pool cleanser dUTPase is highly expressed in CRC and is an attractive target for potentiating anticancer activity of chemotherapy. The purpose of the current work was to investigate the activity of P, P-di(2',5'-dideoxy-5'-selenouridinyl)-tetraphosphate (P-SedU), a selenium-modified symmetrically capped dinucleoside with prodrug capabilities that is specifically activated by dUTPase.

Deoxyuridine-5'-triphosphate nucleotidohydrolase (dUTPase), a vital enzyme in pyrimidine metabolism, is a prime target for treating colorectal cancer. Uracil shares structural traits with DNA/RNA bases, prompting exploration by medicinal chemists for pharmacological modifications. Some existing drugs, including thymidylate synthase (TS) and dUTPase inhibitors, incorporate uracil moieties.
