Water-Promoted Chlorination of 2-Mercaptobenzothiazoles

Substituted benzothiazoles play an important role in medicinal chemistry due to their pharmacological properties. Their 2-substituted derivatives are often prepared from 2-chlorobenzothiazoles, which in turn can be synthesized from the 2-mercapto precursor using sulfuryl chloride. In practice, this seemingly straightforward and widely used reaction can be impeded by poor reproducibility and low reaction yields. In this communication, we report that the simple addition of water to the reaction leads to remarkable improvements in reaction efficiency. We attribute this effect to the formation of acid through partial hydrolysis of sulfuryl chloride. This hypothesis is supported by the observation that improved yields were also obtained in the presence of some anhydrous acidic additives. The simple combination of sulfuryl chloride and water reproducibly provides excellent yields for a range of chlorinated products.

Rapid Access to a Broad Range of 6′-Substituted Firefly Luciferin Analogues Reveals Surprising Emitters and Inhibitors

Light-emitting firefly luciferin analogues contain electron-donating groups in the 6′-position, but the scope of known 6′-substitution remains narrow. A two-step route to a broad range of 6′-substituted luciferin analogues was developed to fill this void and enable more extensive study of the 6′-functionality. This chemistry allowed direct access to "caged" amide and bright azetidine analogues, but also revealed thioether inhibitors and unexpectedly luminogenic aryl amine derivatives.

DERIVATIVES OF HETEROARYLSULFONAMIDES, THEIR PREPARATION AND THEIR APPLICATION IN HUMAN THERAPY

The present invention concerns derivatives of heteroarylsulfonamides, notably as blockers of Kv potassium channels, and more particularly of channels Kv1.5, Kv4.3 or Kv11.1, their application in clinical therapy and their preparation methods. These compounds correspond to the following general formula (I): where R1 represents one or more substituents of the phenyl core X such as: hydrogen, halogen, trifluoromethyl, trifluoromethoxy, linear or branched C1-C4 alkyl, or linear or branched C1-C4 alkoxy, A represents oxygen or sulphur, B represents nitrogen when n=1 or 2 and D represents —C(═O)—, or B represents CH when n=0 and D represents —CH2O— or when n=1 and D represents —O—, R2 represents a hydrogen, a methyl, a fluorine or chlorine atom or a methoxy, HetAr represents a pyridyl or quinolyl group, possibly substituted by a group such as a linear or branched C1-C4 alkyl, a linear or branched C1-C4 alkoxy, a halogen, or a trifluoromethyl, and to their pharmaceutically acceptable salts.

Preparation, antibacterial evaluation and preliminary structure-activity relationship (SAR) study of benzothiazol- and benzoxazol-2-amine derivatives

In this study, a novel benzothiazol- and benzooxazol-2-amine scaffold with antibacterial activity was designed and synthesized. Preliminary structure-activity relationship analysis displayed that compound 8t with a 5,6-difluorosubstituted benzothiazole was found to be a potent inhibitor of Gram-positive pathogens, and exhibited some potential against drug-resistant bacteria and without cytotoxicity in therapeutic concentrations. In addition, molecular docking studies indicated that Staphylococcus aureus methionyl-tRNA synthetase might be the possible target of these compounds. Taken together, the present study provides an effective entry to the synthesis of a good lead for subsequent optimization and a new small molecule candidate drug for antibacterial therapeutics.

Synthesis and antibacterial evaluation of a novel series of 2-(1,2-dihydro-3-oxo-3H-pyrazol-2-yl)benzothiazoles

The 2-(1,2-dihydro-3-oxo-3H-pyrazol-2-yl)benzothiazole scaffold was selected as a central core structure for the discovery of novel antibacterial compounds. A systematic variation of the substituents on the oxo-pyrazole moiety, as well as on the benzo moiety, led to the creation of a small and focused library of benzothiazoles that was subjected to antibacterial screening. In a first round of screening, activity of the compounds against six representative microorganisms was established. For the most potent congeners, MIC values against S. aureus and P. aeruginosa were determined. The structure-activity relationship study clearly revealed that subtle structural variations influence the antibacterial activity to a large extent. The most potent congeners displayed MIC values of 3.30 μM.

Ferulic acid and benzothiazole dimer derivatives with high binding affinity to β-amyloid fibrils

New ferulic acid and benzothiazole dimer derivatives were synthesized and evaluated by in vitro competition assay using [125I]TZDM for their specific binding affinities to Aβ fibrils. In particular, 4a showed the most excellent binding affinity (Ki = 0.53 nM), compared to PIB (Ki = 0.77 nM), for benzothiazole binding sites of Aβ1-42 fibrils. This result suggests a possibility of a potential AD diagnostic probe for detection of Aβ fibrils.
