Facile synthesis and in vitro activity of n-substituted 1,2-benzisothiazol-3(2H)-ones against dengue virus NS2BNS3 protease

Several new N-substituted 1,2-benzisothiazol-3(2H)-ones (BITs) were synthesised through a facile synthetic route for testing their anti-dengue protease inhibition. Contrary to the conventional multistep synthesis, we achieved structurally diverse BITs with excellent yields using a two-step, one-pot reaction strategy. All the synthesised compounds were prescreened for drug-like properties using the online Swiss Absorption, Distribution, Metabolism and Elimination (SwissADME) model, indicating their favourable pharmaceutical properties. Thus, the synthesised BITs were tested for inhibitory activity against the recombinant dengue virus serotype-2 (DENV-2) NS2BNS3 protease. Dose–response experiments and computational docking analyses revealed that several BITs bind to the protease in the vicinity of the catalytic triad with IC50 values in the micromolar range. The DENV2 infection assay showed that two BITs, 2-(2-chlorophenyl)benzo[d]isothiazol-3(2H)-one and 2-(2,6-dichlorophenyl)benzo[d]isothiazol-3(2H)-one, could suppress DENV replication and virus infectivity. These results indicate the potential of BITs for developing new anti-dengue therapeutics.

Novel synthesis method of N-substituted benzisothiazoline-3-ketone derivative

The invention discloses a novel synthesis method of an N-substituted benzisothiazoline-3-ketone derivative. The preparation method comprises the following steps: by taking a dithiosalicylic acid derivative and sulfur as raw materials, introducing chlorine or bromine to obtain a halogenated thiobenzoyl halide derivative, then preferably dropwise adding a mixed solution of primary amine and tertiaryamine, and carrying out reaction and ring closing to obtain the N-substituted benzisothiazole-3-ketone. The method disclosed by the invention is simple in process, safe and controllable, and easy forindustrial large-scale production.

Benzisothiazolinone Derivatives as Potent Allosteric Monoacylglycerol Lipase Inhibitors That Functionally Mimic Sulfenylation of Regulatory Cysteines

We describe a set of benzisothiazolinone (BTZ) derivatives that are potent inhibitors of monoacylglycerol lipase (MGL), the primary degrading enzyme for the endocannabinoid 2-arachidonoyl-sn-glycerol (2-AG). Structure-activity relationship studies evaluated various substitutions on the nitrogen atom and the benzene ring of the BTZ nucleus. Optimized derivatives with nanomolar potency allowed us to investigate the mechanism of MGL inhibition. Site-directed mutagenesis and mass spectrometry experiments showed that BTZs interact in a covalent reversible manner with regulatory cysteines, Cys201 and Cys208, causing a reversible sulfenylation known to modulate MGL activity. Metadynamics simulations revealed that BTZ adducts favor a closed conformation of MGL that occludes substrate recruitment. The BTZ derivative 13 protected neuronal cells from oxidative stimuli and increased 2-AG levels in the mouse brain. The results identify Cys201 and Cys208 as key regulators of MGL function and point to the BTZ scaffold as a useful starting point for the discovery of allosteric MGL inhibitors.

DIPHOSPHONATE COMPOUND AND A METHOD FOR PREPARING THE SAME AND AN APPLICATION OF THE SAME

The present disclosure relates to a new diphosphonate compound, and the method to prepare the above new diphosphonate compound. The new diphosphonate compound exhibits an activity in inhibiting osteoclast equivalent to alendronate sodium, and a higher activity in affecting the proliferation of osteoplast than the positive control compounds, but the positive control exhibits a weaker effect on osteoblast proliferation. In experimental examples, an administration schedule for the diphosphonate compound is provided.

Inhibition of thioredoxin reductase by a novel series of bis-1,2-benzisoselenazol-3(2H)-ones: Organoselenium compounds for cancer therapy

Thioredoxin reductase (TrxR) is critical for cellular redox regulation and is involved in tumor proliferation, apoptosis and metastasis. Its C-terminal redox-active center contains a cysteine (Cys497) and a unique selenocysteine (Sec498), which are exposed to solvent and easily accessible. Thus, it is becoming an important target for anticancer drugs. Selective inhibition of TrxR by 1,2-(bis-1,2-benzisoselenazol-3(2H)-one)ethane (4a) prevents proliferation of several cancer cell lines both in vivo and in vitro. Using the structure of 4a as a starting point, a series of novel bis-1,2-benzisoselenazol-3(2H)-ones was designed, prepared and tested to explore the structure-activity relationships (SARs) for this class of inhibitor and to improve their potency. Notably, 1,2-(5,5′-dimethoxybis(1,2-benzisoselenazol-3(2H)-one))ethane (12) was found to be more potent than 4a in both in vitro and in vivo evaluation. Its binding sites were confirmed by biotin-conjugated iodoacetamide assay and a SAR model was generated to guide further structural modification.

Crucial role of selenium in the virucidal activity of benzisoselenazol- 3(2h)-ones and related diselenides

Various N-substituted benzisoselenazol-3(2H)-ones and their non-seleniumcontaining analogues have been synthesized and tested against selected viruses (HHV-1, EMCV and VSV) to determine the extent to which selenium plays a role in antiviral activity. The data presented here show that the presence of selenium is crucial for the antiviral properties of benzisoselenazol-3(2H)-ones since their isostructural analogues having different groups but lacking selenium either did not show any antiviral activity or their activity was substantially lower. The open-chain analogues of benzisoselenazol- 3(2H)-ones-diselenides also exhibited high antiviral activity while selenides and disulfides were completely inactive towards model viruses.
