- Synthesis, characterization, and biological evaluation of new derivatives targeting MbtI as antitubercular agents
-
Tuberculosis (TB) causes millions of deaths every year, ranking as one of the most dangerous infectious diseases worldwide. Because several pathogenic strains of Mycobacterium tuberculosis (Mtb) have developed resistance against most of the established anti-TB drugs, new therapeutic options are urgently needed. An attractive target for the development of new antitubercular agents is the salicylate synthase MbtI, an essential enzyme for the mycobacterial siderophore biochemical machinery, absent in human cells. A set of analogues of I and II, two of the most potent MbtI inhibitors identified to date, was synthesized, characterized, and tested to elucidate the structural requirements for achieving an efficient MbtI inhibition and a potent antitubercular activity with this class of compounds. The structure-activity relationships (SAR) here discussed evidenced the importance of the furan as part of the pharmacophore and led to the preparation of six new compounds (IV-IX), which gave us the opportunity to examine a hitherto unexplored position of the phenyl ring. Among them emerged 5-(3-cyano-5-(trifluoromethyl)phenyl)furan-2-carboxylic acid (IV), endowed with comparable inhibitory properties to the previous leads, but a better antitubercular activity, which is a key issue in MbtI inhibitor research. Therefore, compound IV offers promising prospects for future studies on the development of novel agents against mycobacterial infections.

- Synthesis and anti-inflammatory activity of 1,2-3-substituted 2a1,4,5-triazacyclopenta[cd]indene derivatives
-
The present study reports the synthesis of 1,2-3-substituted-2a1,4,5-triazacyclopenta[cd]indene derivatives. The synthetic methodology includes some of the prominent reaction steps as specified in sequence (i) Bromination of acetophenones (ii) Condensation of 2-bromo-1-(substituted phenyl) ethanone derivatives with 2-aminopyrimidine, and (iii) Coupling of imidazo[1,2-a]pyrimidine derivatives with 1,2-diaryl/diaklylethynes. The structures of the newly synthesized derivatives have been determined by 1H NMR, 13C NMR, LC-MS, and IR spectral analysis. Furthermore, these derivatives were screened for their preliminary anti-inflammatory activities using Carrageenan induced paw edema test method. These promising screening results suggested a huge potential for the molecular diversity from present compounds that can be inflated to better lead candidates.

- Switching reversibility to irreversibility in glycogen synthase kinase 3 inhibitors: Clues for specific design of new compounds
-
Development of kinase-targeted therapies for central nervous system (CNS) diseases is a great challenge. Glycogen synthase kinase 3 (GSK-3) offers a great potential for severe CNS unmet diseases, being one of the inhibitors on clinical trials for different tauopathies. Following our hypothesis based on the enhanced reactivity of residue Cys199 in the binding site of GSK-3, we examine here the suitability of phenylhalomethylketones as irreversible inhibitors. Our data confirm that the halomethylketone unit is essential for the inhibitory activity. Moreover, addition of the halomethylketone moiety to reversible inhibitors turned them into irreversible inhibitors with IC50 values in the nanomolar range. Overall, the results point out that these compounds might be useful pharmacological tools to explore physiological and pathological processes related to signaling pathways regulated by GSK-3 opening new avenues for the discovery of novel GSK-3 inhibitors.

- Synthesis of 3-substituted benzamides and 5-substituted isoquinolin-1(2H)-ones and preliminary evaluation as inhibitors of poly(ADP-ribose)polymerase (PARP)
-
Inhibitors of poly(ADP-ribose)polymerase (PARP) inhibit repair of damaged DNA and thus potentiate radiotherapy and chemotherapy of cancer. 3-Substituted benzamides and 5-substituted isoquinolin-1-ones have been synthesised and evaluated for inhibition of PARP. Reduction of 3-(bromoacetyl)benzamide, followed by treatment with base, gave RS-3-oxiranylbenzamide. Reduction of 3-(hydroxyacetyl)benzonitrile with bakers' yeast gave the R-diol which was converted to R-3-(1,2-dihydroxyethyl)benzamide. Similar reduction of 3-(acetoxyacetyl)benzonitrile led towards the S-diol which was converted to its cyclic acetonide. E-2-(2,6-Dicyanophenyl)-N,N-dimethylethenamine was formed by condensation of 2,6-dicyanotoluene with dimethylformamide dimethyl acetal (DMFDMA); cyclisation under acidic conditions afforded 5-cyanoisoquinolin-1-one. Heck coupling of 5-iodoisoquinolin-1-one with propenoic acid formed E-3-(1-oxoisoquinolin-5-yl)propenoic acid. 3-Oxiranylbenzamide, 5-bromoisoquinolin-1-one and 5-iodoisoquinolin-1-one were among the most potent inhibitors of PARP activity in a preliminary screen in vitro.

- Inhibitors of acyl-coA:cholesterol O-acyltransferase. 2. Identification and structure-activity relationships of a novel series of N-alkyl-N- (heteroaryl-substituted benzyl)-N'-arylureas
-
A series of N-alkyl-N-(heteroaryl-substituted benzyl)-N'-arylurea and related derivatives represented by 2 and 3 have been prepared and evaluated for their ability to inhibit acyl-CoA:cholesterol O-acyltransferase in vitro and to lower plasma cholesterol levels in cholesterol-fed rats in vivo. Among these novel compounds, the type 3 series was superior. A pyrazol-3-yl group on the N-benzyl group of this trisubstituted urea (i.e. 3, Ar1 = pyrazol-3- yl) was identified as a heteroaromatic ring providing a good profile of biological activity. As a result of optimization of the combination with the N-alkyl group (R) and N-aryl group (At3), compound 3aq (FR186054) was identified as a new, orally efficacious ACAT inhibitor, which exhibited potent in vitro ACAT inhibitory activity (rabbit intestinal microsomes IC50 = 99 nM) and excellent hypocholesterolemic effects in cholesterol-fed rats, irrespective of administration mode (ED50 = 0.046 mg/kg dosed via the diet, ED50 = 0.44 mg/kg administered by gavage in PEG400 vehicle). Moreover, a toxicological study revealed compound 3aq to be nontoxic to the adrenal glands of dogs when tested at a single dose of 10 mg/kg po.

- Photochemical Generation of Radical Anions of Photolabile Aryl Ketones
-
The radical anions of a series of substituted α-(aryloxy)acetophenones have been generated by trapping the solvated electron produced by 355-nm laser-induced photoionization of 4,4'-dimethoxystilbene in either acetonitrile or dimethylformamide (DMF).The radical anion of the parent ketone, α-phenoxyacetophenone, has λmax at 500 nm and decays with a rate constant 7 x 1E5 s-1.This rate constant reflects the rate of β-cleavage to generate phenoxide ion and phenylacyl radical.The rate constant for β-cleavage decreases for ketones with electron donating substituents in the α-aryloxy ring.Substituent effects on the acetophenone ring are in the opposite direction, and many of the 4-substituted (aryloxy)acetophenones have half-lives in excess of 10 μs that reflect a combination of second order processes and are not limited by β-cleavage.The generality of the photoionization/electron trapping method for the generation of radical anions of ketones with short-lived excited states that preclude direct excitation is illustrated by its application to other aryl ketones that undergo α-cleavage, β-phenyl quenching, and intramolecular hydrogen abstraction reactions.
