Discovery of highly potent and selective influenza virus neuraminidase inhibitors targeting 150-cavity

Encouraged by our earlier discovery of N1-selective inhibitors, the 150-cavity of influenza virus neuraminidases (NAs) could be further exploited to yield more potent oseltamivir derivatives. Herein, we report the design, synthesis and biological evaluation of a series of novel oseltamivir derivatives via the structural modifications at C5–NH2 of oseltamivir targeting 150-cavity. Among them, compound 5c bearing 4-(3-methoxybenzyloxy)benzyl group exhibited the most potent activity, which was lower or modestly improved activities than oseltamivir carboxylate (OSC) against N1 (H1N1), N1 (H5N1) and N1 (H5N1–H274Y). Specifically, there was 30-fold loss of activity against the wild-type strain H1N1. However, 5c displayed 4.85-fold more potent activity than OSC against H5N1–H274Y NA. Also, 5c demonstrated low cytotoxicity in vitro and no acute toxicity in mice. Molecular docking studies provided insights into the high potency of 5c against N1 and N1–H274Y mutant NAs. Besides, the in silico prediction of physicochemical properties and CYP enzymatic inhibitory ability of representative compounds were conducted to evaluate their drug-like properties.

Evolution of a 4-Benzyloxy-benzylamino Chemotype to Provide Efficacious, Potent, and Isoform Selective PPARα Agonists as Leads for Retinal Disorders

Peroxisome proliferator-activated receptor alpha (PPARα) is expressed in retinal Müller cells, endothelial cells, and in retinal pigment epithelium; agonism of PPARα with genetic or pharmacological tools ameliorates inflammation, vascular leakage, neurodegeneration, and neovascularization associated with retinal diseases in animal models. As such, PPARα is a promising drug target for diabetic retinopathy and age-related macular degeneration. Herein, we report proof-of-concept in vivo efficacy in an streptozotocin-induced vascular leakage model (rat) and preliminary pharmacokinetic assessment of a first-generation lead 4a (A91). Additionally, we present the design, synthesis, and evaluation of second-generation analogues, which led to the discovery of 4u and related compounds that reach cellular potencies 2,700-fold selectivity for PPARα over other PPAR isoforms. These studies identify a pipeline of candidates positioned for detailed PK/PD and pre-clinical evaluation.

Synthesis and biological evaluation of novel 4-oxo-5-cyano thiouracil derivatives as SecA inhibitors

The continuous emergence of drug-resistant strains of bacteria poses an urgent risk to human health and dictates the need for new antimicrobials. Along this line, we have been working on developing inhibitors of SecA, a key component of the bacterial Sec-dependent secretion machinery. Herein, we describe the synthesis and antimicrobial evaluation of 6-oxo-1,6-dihydropyrimidine- 5-carbonitrile derivatives as potential SecA inhibitors.

Potential anti-neuroinflammatory NF-кB inhibitors based on 3,4-dihydronaphthalen-1(2H)-one derivatives

Nuclear factor kappa B (NF-кB) inhibition represents a new therapeutic strategy for the treatment of neuroinflammatory diseases. In this study, a series of 3,4-dihydronaphthalen-1(2H)-one (DHN; 6a-n, 7a-c) derivatives were synthesised and characterised by NMR and HRMS. We assessed the toxicity and anti-neuroinflammatory properties of these compounds and found that 6m showed the greatest anti-neuroinflammatory properties, with relatively low toxicity. Specifically, 6m significantly reduced reactive oxygen species production, down-regulated the expression of NOD-like receptor pyrin domain-containing protein 3 (NLRP3), apoptosis-associated speck-like protein containing a CARD (ASC), and caspase-1 and prevented lipopolysaccharide-stimulated BV2 microglia cells polarisation towards an M1 phenotype. Furthermore, 6m significantly decreased IκBα and NF-кB p65 phosphorylation, thus inhibiting the NF-кB signalling pathway. This suggests that 6m may be explored as a functional anti-neuroinflammatory agent for the treatment of inflammatory diseases in the central nervous system, such as multiple sclerosis, traumatic brain injury, stroke and spinal cord injury.

Synthesis and evaluation of the antibacterial activities of aryl substituted dihydrotriazine derivatives

Five series of dihydrotriazine derivatives containing chalcone (13a–i), phenoxy acetophenone (14a–b), benzyl benzene (15a–c), naphthoxyl acetophenone (16a–b) and benzyl naphthalene (17a–h) moieties were designed and synthesized. The antibacterial and antifungal activities of these compounds were evaluated against several strains of Gram-positive and Gram-negative bacteria, as well as a single fungus. Compound 17h was found to be the most potent of all of the compounds tested, with an MIC value of 0.5 μg/mL against several Gram-positive (Staphylococcus aureus 4220 and QRSA CCARM 3505) and Gram-negative (Escherichia coli 1924) strains of bacteria. However, this compound was inactive against Pseudomonas aeruginosa 2742 and Salmonella typhimurium 2421, indicating that its antibacterial spectrum is similar to those of the positive controls gatifloxacin and moxifloxacin. The cytotoxic activity of the compound 13i, 16b and 17h was assessed in Human normal liver cells.

Novel cinnamic acid–tryptamine hybrids as potent butyrylcholinesterase inhibitors: Synthesis, biological evaluation, and docking study

A novel series of cinnamic acid–tryptamine hybrids was designed, synthesized, and evaluated as cholinesterase inhibitors. Anticholinesterase assays showed that all of the synthesized compounds displayed a clearly selective inhibition of butyrylcholinesterase (BChE), but only a moderate inhibitory effect toward acetylcholinesterase (AChE) was detected. Among these cinnamic acid–tryptamine hybrids, compound 7d was found to be the most potent inhibitor of BChE with an IC50 value of 0.55 ± 0.04 μM. This compound showed a 14-fold higher inhibitory potency than the standard drug donepezil (IC50 = 7.79 ± 0.81 μM) and inhibited BChE through a mixed-type inhibition mode. Moreover, a docking study revealed that compound 7d binds to both the catalytic anionic site (CAS) and the peripheral anionic site (PAS) of BChE. Also, compound 7d was evaluated against β-secretase, which exhibited low activity (inhibition percentage: 38%).

New promising porphyrazine-based agents for optical theranostics of cancer

New porphyrazine bases containing peripheral benzyloxyphenyl groups have been synthesized by the template method. The procedure includes condensation of aromatic aldehydes with malononitrile, transformation of arylmethylidenemalononitriles to arylethenetricarbonitriles, template assembly of porphyrazine macrocycle on bis(indenyl)ytterbium(II) complex, and removal of the central metal ion. Luminescence properties of the synthesized porphyrazines and their dependence on the viscosity of the medium were studied, and the light and dark toxicities of the porphyrazines have been estimated. The obtained results suggest the possibility of using these porphyrazines as optical theranostic agents of new generation.
