Built upon the catalytic mechanism-based pan-SIRT1/2/3 inhibitory warhead L-2-amino-7-carboxamidoheptanoic acid (L-ACAH, a close structural analog of N(ε)-acetyl-lysine) that our laboratory discovered recently, in the current study, its carboxamide NH2-ethylated analog was found to be a ∼2.4-6.6-fold stronger SIRT1/2/3 inhibitory warhead than L-ACAH. Carboxamide NH2-dodecylated and carboxymethylated analogs of L-ACAH were also identified as potent SIRT6 and SIRT5 inhibitory warheads, respectively.

The tetrazole group is here proposed as a zinc-binding warhead for the inhibition of the metalloenzyme carbonic anhydrases. A set of synthesized derivatives incorporating the tetrazole moiety were evaluated as inhibitors against a panel of human isoforms, exhibiting values spanning between the submicromolar and low-to-medium micromolar ranges (0.62-19.

In response to the escalating crisis of antimicrobial resistance (AMR), there is an urgent need to research and develop novel antibiotics. This study presents the synthesis and assessment of innovative 4-aminoquinoline-benzohydrazide-based molecular hybrids bearing aryl aldehydes () and substituted isatin warheads (), characterized using multispectroscopic techniques with high purity confirmed by HRMS. The compounds were evaluated against a panel of clinically relevant antibacterial strains including the Gram-positive , , and and a Gram-negative bacterial strain.

Despite the vital role of iron and vulnerability of iron metabolism in disease states, it remains largely unknown whether chemicals interacting with cellular proteins are responsible for perturbation of iron metabolism. We previously demonstrated that cisplatin was an inhibitor of the iron regulatory system by blocking IRP2 (iron regulatory protein 2) binding to an iron-responsive element (IRE) located in the 3'- or 5'-UTR (untranslated region) of key iron metabolism genes such as transferrin receptor 1 (TfR1) and ferritin mRNAs. To guide the development of new chemical probes to modulate the IRP-IRE regulatory system, we used an artificial intelligence (AI)-based ligand design and screened a chemical library composed of cysteine-reactive warheads.

Cathepsin C (Cat C) is a potential candidate for addressing inflammatory conditions associated with neutrophil serine proteases (NSPs). The high reactivity of electrophilic warheads and the metabolic instability of peptide structures are among the primary challenges in developing potent cathepsin C inhibitors. Compound 36, a lead compound derived from compound 1 through structure-based drug design and structure-activity relationship (SAR), exhibited strong Cat C inhibitory activity with an IC value of 437 nM.
