We synthesized fluoro- and hydroxy-containing octahydro-2H-chromenes by the Prins reaction starting from a monoterpenoid (-)-isopulegol and a wide range of aromatic aldehydes in the presence of the BF∙EtO/HO system acting as both an acid catalyst and a fluorine source. Activity of the produced compounds against the influenza A/Puerto Rico/8/34 (H1N1) virus was studied. The highest activity was demonstrated by fluoro- (11i) and hydroxy-containing (10i) derivatives of 2,4,6-trimethoxybenzaldehyde. The most pronounced virus-inhibiting effect of compounds 10i and 11i was observed at an early stage of infection. These compounds were supposed to be capable of binding to viral hemagglutinin, which is an agreement with data on the effect of compounds 10i and 11i on the viral fusogenic activity as well as by molecular docking studies.

The antibacterial efficacy of some newly developed bis- and C3-carboxylic moieties of fluoroquinolone-linked triazole conjugates was studied. Twenty compounds from two different series of triazoles were synthesized using click chemistry and evaluated for their antibacterial activity against a Gram-positive strain, (ATCC29212), and its clinical isolate and a Gram-negative bacterial strain, (ATCC25922), and its clinical isolate. Among the compounds, 7, 9a, 9d, 9i, 10(a-d), and 10i showed excellent activity with MIC values of up to 6.

Sugar mimics are valuable tools in medicinal chemistry, offering the potential to overcome the limitations of carbohydrate inhibitors, such as poor pharmacokinetics and non-selectivity. In our continued efforts to develop heterocyclic galectin-1 inhibitors, we report the synthesis and characterization of thiazole-linked coumarin piperazine hybrids (10a-10i) as Gal-1 inhibitors. The compounds were characterized using H NMR, C NMR and HRMS.

A novel series of substituted thiazolo[5,4-b]pyridine analogues were rationally designed and synthesized via a multi-step synthetic pathway, including Suzuki cross-coupling reaction. The anticancer activity of all forty-five synthesized derivatives was evaluated against HCC827, H1975, and A549 cancer cell lines utilizing the standard MTT assay. A significant number of the thiazolo[5,4-b]pyridine derivatives exhibited potent anticancer activity.

Ribonuclease H (RNase H) was identified as an important target for HIV therapy. Currently, no RNase H inhibitors have reached clinical status. Herein, a series of novel thiazolone[3,2-]pyrimidine-containing RNase H inhibitors were developed, based on the hit compound , identified from screening our in-house compound library.

Article Synopsis
  • Two series of hydrazinyl-based benzenesulfonamides were developed from the molecule SLC-0111 and tested for their effects on human carbonic anhydrase (hCA) enzymes.
  • The new compounds showed no significant activity against hCA I, but some demonstrated strong inhibition of hCA II, IX, and XII, particularly compound 10a which was more potent than the existing drug acetazolamide.
  • The most effective compound, 9g, had selective inhibition against hCA IX and XII, indicating the potential for creating targeted treatments for tumor progression without affecting hCA I.
