- Quinolone amides as antitrypanosomal lead compounds with In Vivo activity
-
Human African trypanosomiasis (HAT) is a major tropical disease for which few drugs for treatment are available, driving the need for novel active compounds. Recently, morpholino-substituted benzyl amides of the fluoroquinolone-type antibiotics were identified to be compounds highly active against Trypanosoma brucei brucei. Since the lead compound GHQ168 was challenged by poor water solubility in previous trials, the aim of this study was to introduce structural variations to GHQ168 as well as to formulate GHQ168 with the ultimate goal to increase its aqueous solubility while maintaining its in vitro antitrypanosomal activity. The pharmacokinetic parameters of spray-dried GHQ168 and the newly synthesized compounds GHQ242 and GHQ243 in mice were characterized by elimination half-lives ranging from 1.5 to 3.5 h after intraperitoneal administration (4 mice/compound), moderate to strong human serum albumin binding for GHQ168 (80%) and GHQ243 (45%), and very high human serum albumin binding (>99%) for GHQ242. For the lead compound, GHQ168, the apparent clearance was 112 ml/h and the apparent volume of distribution was 14 liters/kg of body weight (BW). Mice infected with T. b. rhodesiense (STIB900) were treated in a stringent study scheme (2 daily applications between days 3 and 6 postinfection). Exposure to spray-dried GHQ168 in contrast to the control treatment resulted in mean survival durations of 17 versus 9 days, respectively, a difference that was statistically significant. Results that were statistically insignificantly different were obtained between the control and the GHQ242 and GHQ243 treatments. Therefore, GHQ168 was further profiled in an early-treatment scheme (2 daily applications at days 1 to 4 postinfection), and the results were compared with those obtained with a control treatment. The result was statistically significant mean survival times exceeding 32 days (end of the observation period) versus 7 days for the GHQ168 and control treatments, respectively. Spray-dried GHQ168 demonstrated exciting antitrypanosomal efficacy.

- Novel 1,6-naphthyridin-2(1H)-ones as potential anticancer agents targeting Hsp90
-
Hsp90 is an ATP-dependent chaperone known to be overexpressed in many cancers. This way, Hsp90 is an important target for drug discovery. Novobiocin, an aminocoumarin antibiotic, was reported to inhibit Hsp90 targeting C-terminal domain, and showed anti-proliferative properties, leading to the development of new and more active compounds. Consequently, a new set of novobiocin analogs derived from 1,6-naphthyridin-2(1H)-one scaffold was designed, synthesized and evaluated against two breast cancer cell lines. Subsequently, cell cycle progression and apoptosis were conducted on best candidates, finally Western Blot analysis was performed to measure their ability to induce degradation of Hsp90 client proteins.

- COMPOUNDS FOR REGULATING FAK AND/OR SRC PATHWAYS
-
The present application provides novel optionally substituted fused pyridine and pyrimidine bicyclic compounds and pharmaceutically acceptable salts thereof. Also provided are methods for preparing these compounds. These compounds are useful in co-regulating FAK and/or Src activity by administering a therapeutically effective amount of one or more of the compounds to a subject. By doing so, these compounds are effective in treating conditions associated with the dysregulation of the FAK and/or Src pathway. Advantageously, these compounds perform as dual FAK and/or Src inhibitors. A variety of conditions can be treated using these compounds and include diseases which are characterized by inflammation or abnormal cellular proliferation. In one embodiment, the disease is cancer.

- Pyridine-3-carboxamide-6-yl-ureas as novel inhibitors of bacterial DNA gyrase: Structure based design, synthesis, SAR and antimicrobial activity
-
The development of antibacterial drugs based on novel chemotypes is essential to the future management of serious drug resistant infections. We herein report the design, synthesis and SAR of a novel series of N-ethylurea inhibitors based on a pyridine-3-carboxamide scaffold targeting the ATPase sub-unit of DNA gyrase. Consideration of structural aspects of the GyrB ATPase site has aided the development of this series resulting in derivatives that demonstrate excellent enzyme inhibitory activity coupled to potent Gram positive antibacterial efficacy.

The invention relates to dihydronaphthyridines and related compounds; compositions comprising an effective amount of a dihydronaphthyridine or a related compound; and methods for treating or preventing proliferative diseases comprising the administration of an effective amount of a dihydronaphthyridine or a related compound. The present invention discloses the unexpected utility of compounds that inhibit cKIT kinase across a broad range of c-KIT mutations, including complex occurrences of primary mutations (KIT exon 9 or 11) and secondary KIT mutations (exons 13, 14, 17 and 18) that may arise in individual, refractory GIST patients. Also unexpected is the utility of compounds of the present invention to inhibit the problematic exon 17 D816V c-KIT mutation, for which there is currently no effective therapy.
