  Targeting Dormant Tuberculosis Bacilli: Results for Molecules with a Novel Pyrimidone Scaffold

  摘要：

  Our inability to completely control TB has been due in part to the presence of dormant mycobacteria. This also renders drug regimens ineffective and is the prime cause of the appearance of drug‐resistant strains. In continuation of our efforts to develop novel antitubercular agents that especially target dormant mycobacteria, a set of 55 new compounds belonging to the pyrimidone class were designed on the basis of CoMFA and CoMSIA studies, and these were synthesized and subsequently tested against both the dormant and virulent BCG strain of M. tuberculosis. Some novel compounds have been identified which selectively inhibit the dormant tuberculosis bacilli with significantly low IC50 values. This study reports the second molecule after TMC‐207, having the ability to inhibit tuberculosis bacilli exclusively in its dormant phase. The synthesis was accomplished by a modified multicomponent Biginelli reaction. A classification model was generated using the binary QSAR approach – recursive partitioning (RP) to identify structural characteristics related to the activity. Physicochemical, structural, topological, connectivity indices, and E‐state key descriptors were used for generation of the decision tree. The decision tree could provide insights into structure–activity relationships that will guide the design of more potent inhibitors.

  The synthesis of various dihydropyrimidinone derivatives bearing carbamoyl moieties in 5-position under reflux conditions and microwave irradiation is described. An efficient three-component Biginelli reaction using catalytic amounts of zirconium(IV) chloride as an efficient catalyst leads to the formation of these compounds.

  Dehydrogenation of various 2-oxo-1,2,3.4-tetrahydropyrimidine-5-carboxamides (THPMs) to 2-oxo-1,2-dihydropyrimidine-5-carboxamides (DHPMs) using tetrabutylammonium peroxydisulfate (TBAPS) as an efficient oxidizing agent under thermal and sono-thermal conditions has been investigated. In contrast to the thermal reaction, a decrease of the amount of oxidant and an increase of the rate of reaction are observed by simultaneously applying heat and ultrasound. The nature of both C-4 and C-5 substituents on the heterocyclic ring influences the rate of reaction under both conditions. The proposed electron-transfer-induced dehydrogenation in this study is supported by conductometric studies. (C) 2010 Elsevier B.V. All rights reserved.

  an oxygen or argon atmosphere on the rate of reaction. The rate of reaction is faster under argon than under oxygen and is influenced by the nature of the substituent on the 4- and 5-positions of the THPM ring. Furthermore, it is found that the dehydrogenation of THPM-amides is faster than that of the corresponding 5-ethoxycarbonyl- and 5-acetyl-THPMs. In contrast to the solution photochemistry, no
