The current monkeypox outbreaks during the COVID-19 pandemic have reignited interest in orthopoxvirus antivirals. Monkeypox belongs to Orthopoxvirus genus of Poxviridae family, which also includes variola virus, vaccinia and cowpox virus. Two orally bioavailable drugs, tecovirimat brincidofovir, been approved for treating smallpox infections. Given their human safety profiles vivo antiviral efficacy animal models, both drugs recommended treat infection. To facilitate development additional antivirals, we summarize activity, mechanism action, resistance This perspective covers direct-acting host-targeting antivirals with an emphasis on drug candidates showing models. We hope speed discovery by providing medicinal chemists insights into prioritizing proper targets hits further development.

The COVID-19 pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has presented an enormous challenge to health care systems and medicine. As a result of global research efforts aimed at preventing effectively treating SARS-CoV-2 infection, vaccines with fundamentally new mechanisms action some small-molecule antiviral drugs targeting key proteins in the viral cycle have been developed. most effective drug approved date for treatment is PaxlovidTM, which combination two protease inhibitors, nirmatrelvir ritonavir. Nirmatrelvir reversible covalent peptidomimetic inhibitor main (Mpro) SARS-CoV-2, enzyme plays crucial role reproduction. In this combination, ritonavir serves as pharmacokinetic enhancer, it irreversibly inhibits cytochrome CYP3A4 responsible rapid metabolism nirmatrelvir, thereby increasing half-life bioavailability nirmatrelvir. tutorial review, we summarize development pharmaceutical chemistry aspects Paxlovid, covering evolution warhead design, synthesis mechanism well its inhibition mechanism. efficacy Paxlovid novel virus mutants also overviewed.

The revolutionary progress in cancer immunotherapy, particularly the advent of immune checkpoint inhibitors, marks a significant milestone fight against malignancies. However, majority clinically employed inhibitors are monoclonal antibodies (mAbs) with several limitations, such as poor oral bioavailability and immune-related adverse effects (irAEs). Another major limitation is restriction efficacy mAbs to subset patients, which triggered extensive research efforts identify alternative approaches targeting checkpoints aiming overcome restricted mAbs. This comprehensive review aims explore cutting-edge developments checkpoints, focusing on both small molecule- peptide-based approaches. By delving into drug discovery platforms, we provide insights diverse strategies optimize molecules peptides checkpoints. In addition, discuss recent advances nanomaterials carriers, providing basis for development platforms immunotherapy. Ongoing focused peptide-inspired agents paves way developing orally bioavailable next-generation immunotherapies.

Within the canonical repertoire of amino acid involved in protein biogenesis, proline plays a unique role as an presenting modified backbone rather than side-chain. Chemical structures that mimic but introduce changes into its specific molecular features are defined analogues. This review article summarizes existing chemical, physicochemical, and biochemical knowledge about this peculiar family structures. We group analogues from following compounds: substituted prolines, unsaturated fused structures, ring size homologues, heterocyclic, e.g., pseudoproline, bridged proline-resembling overview (1) occurrence nature their chemical synthesis, (2) physicochemical properties including conformation

SARS-CoV-2 main protease, Mpro, is responsible for processing the viral polyproteins into individual proteins, including protease itself. Mpro a key target of anti-COVID-19 therapeutics such as nirmatrelvir (the active component Paxlovid). Resistance mutants identified clinically and in passage assays contain combination site mutations (e.g., E166V, E166A, L167F), which reduce inhibitor binding enzymatic activity, non-active P252L, T21I, L50F), restore fitness replication. To probe role rescue, here we use an triple mutant (L50F/E166A/L167F) that confers drug resistance with level similar to wild-type. By comparing peptide full-length protein substrates, demonstrate substrate involves more than residues site. Particularly, L50F other can enhance dimer-dimer interactions help place nsp5-6 at enzyme catalytic center. The structural activity data L50F, L50F/E166A/L167F, others underscore importance considering whole studying interactions, offers important insights function, development, design.
