Copper dipyridinedichloride (CuPy2Cl2) has been found to be an efficient catalyst for the synthesis of N-arylanthranilic acids from ortho halobenzoic acids and aromatic amines under microwave irradiation. Some of the advantages of this method are high chemoselectivity, ease of operation, less reaction times and high yields. (61–98%).

Disclosed are compositions and methods for the prevention and/or treatment of diseases which are pathophysiologically related to GPR35, and/or GPR35-hERG signaling complex. For example, disclosed are compounds for preventing and/or treating diseases which are pathophysiologically related to GPR35 in a subject. The compounds having a formula (I), (II) or (III):
Indonesia has played a vital role in the security of South-East Asia for more than 30 years, both through its prominent position in ASEAN and the ARF and through the stability and longevity of the Suharto regime. The central theme of this article emphasizes that peace and stability in Indonesia are the key to peace and stability in the South-East Asian region. However, instability within ASEAN countries themselves and the risk of serious upheaval in Indonesia have the potential to infect other parts of South-East Asia. The author assesses Indonesia's role in shaping regional security and the country's prospects for a successful democratic future in which the West has a strong interest in encouraging the more moderate Indonesian Islamic elements to build enduring and democratic political institutions.

synthesized two FA analogues, namely, 2-(naphthalen-1-ylamino)-benzoic acid and 2-(naphthalen-2-ylamino)-benzoic acid (NBAs), and investigated their polymorphism. Contrary to the lack of polymorphism in FA, we discovered two crystal forms (1-I, 1-II, 2-I, and 2-II) for each of the two compounds. We characterized the twopolymorphic systems with single-crystal X-ray diffraction, powder X-ray diffraction

DMAP-catalysed Curtius rearrangement and intramolecular cyclisation cascade reaction of 2-substituted aryl carboxylic acids with organicazides for the first time. This protocol features simple operation, broad scope and metal-free conditions, furnishing a broad spectrum of biologically attractive heterocycles. The synthetic virtue of this reaction was demonstrated by gram-scale synthesis and applicability toward
