- Small molecules enhance functional O-mannosylation of Alpha-dystroglycan
-
Alpha-dystroglycan (α-DG), a highly glycosylated receptor for extracellular matrix proteins, plays a critical role in many biological processes. Hypoglycosylation of α-DG results in various types of muscular dystrophies and is also highly associated with progression of majority of cancers. Currently, there are no effective treatments for those devastating diseases. Enhancing functional O-mannosyl glycans (FOG) of α-DG on the cell surfaces is a potential approach to address this unmet challenge. Based on the hypothesis that the cells can up-regulate FOG of α-DG in response to certain chemical stimuli, we developed a cell-based high-throughput screening (HTS) platform for searching chemical enhancers of FOG of α-DG from a large chemical library with 364,168 compounds. Sequential validation of the hits from a primary screening campaign and chemical works led to identification of a cluster of compounds that positively modulate FOG of α-DG on various cell surfaces including patient-derived myoblasts. These compounds enhance FOG of α-DG by almost ten folds, which provide us powerful tools for O-mannosylation studies and potential starting points for the development of drug to treat dystroglycanopathy.

- A novel practical synthesis of benzothiazoles via Pd-catalyzed thiol cross-coupling
-
A convenient synthesis of substituted benzothiazoles from 2-bromoanilides has been accomplished. The various 2-bromoanilides were reacted with an alkyl thiolate in high yields using a palladium catalyst. The resulting sulfides were easily converted to the corresponding benzothiazoles via the simultaneous generation of thiols and condensation under basic or acidic conditions.

- Synthesis and evaluation of novel bacterial rRNA-binding benzimidazoles by mass spectrometry
-
A series of novel benzimidazoles were efficiently synthesized using both solution- and solid-phase chemistry. These compounds were found to bind to the bacterial 16S ribosomal RNA A-site with micromolar affinities using unique mass spectrometry-based assays.

- PROLINE DERIVATIVES AND USE THEREOF AS DRUGS
-
The present invention aims at providing compounds having therapeutic effects due to a DPP-IV inhibitory action, and satisfactory as pharmaceutical products. The present inventors have found that derivatives having a substituent introduced into the γ-position of proline represented by the formula (I) wherein each symbol is as defined in the specification, have a potent DPP-IV inhibitory activity, and completed the present invention by increasing the stability.

- Non-imidazole histamine H3 ligands, part 2: New 2-substituted benzothiazoles as histamine H3 antagonists
-
New, non-imidazole histamine H3 receptor antagonists were prepared and in vitro tested as H3 receptor antagonists measured as the electrically evoked contraction of the guinea-pig jejunum. The 2-(1-piperidinyl)- and 2- (1-pyrrolidinyl)benzothiazoles show no or very poor activity; 2-[1-(4- amino)piperidinyl]- and 2-(1,2-ethanediamino)- and (2-(1,3- propanediamino)derivatives of benzothiazole possess weak activity at H3 receptors, whereas 2-(4-piperidinyl)benzothiazoles and 2-[1-(4- piperazinyl)]benzothiazoles show moderate to good activity. Lipophilic and not-too-bulky substituents like n-propyl attached to the nitrogen at the piperazine or piperidine ring lead to potent H3 receptor antagonists with pA2 values ranging from 7.0 to 7.2. The structure-activity relationships for different substitution patterns are discussed.

- Synthesis and structure-activity relationship of new piperidinyl and piperazinyl derivatives as antiallergics
-
A series of piperazinebenzothiazoles 3-5, piperazinebenzimidazoles 6-12, piperidinobenzothiazoles 14-45, piperidinobenzoxazoles 46-52 and piperidinobenzimidazoles 53-129 has been synthesized and their antiallergic activity evaluated by means of the passive cutaneous anaphylaxis (PCA) assay. Structure-activity relationships are discussed and related to classical antihistaminics. Piperidino derivatives with an aryl group linked to the nitrogen atom by an ethyl chain are the most active compounds, with ID50 1 mg/kg po. Some of these compounds are more potent antiallergics than astemizole and terfenadine.
