A series of new Olaparib derivatives was designed and synthesized, and their inhibitory activities against poly (ADP-ribose) polymerases-1 (PARP-1) enzyme and cancer cell line MDA-MB-436 in vitro were evaluated. The results showed that compound 5l exhibited the most potent inhibitory effects on PARP-1 enzyme (16.10 +/- 1.25 nM) and MDA-MB-436 cancer cell (11.62 +/- 2.15 mu M), which was close to that of Olaparib. As a PARP-1 inhibitor had been reported to be viable to neuroprotection, in order to search for new multitarget-directed ligands (MTDLs) for the treatment of Alzheimer’s disease (AD), the inhibitory activities of the synthesized compounds against the enzymes AChE (from electric eel) and BChE (from equine serum) were also tested. Compound 5l displayed moderate BChE inhibitory activity (9.16 +/- 0.91 mu M) which was stronger than neostigmine (12.01 +/- 0.45 mu M) and exhibited selectivity for BChE over AChE to some degree. Molecular docking studies indicated that 5l could bind simultaneously to the catalytic active of PARP-1, but it could not interact well with huBChE. For pursuit of PARP-1 and BChE dual-targeted inhibitors against AD, small and flexible non-polar groups introduced to the compound seemed to be conducive to improving its inhibitory potency on huBChE, while keeping phthalazine-1-one moiety unchanged which was mainly responsible for PARP-1 inhibitory activity. Our research gave a clue to search for new agents based on AChE and PARP-1 dual-inhibited activities to treat Alzheimer’s disease.

The cobalt alkyne complex [(prop-2-ynyl)-2-acetoxybenzoate]dicobalthexacarbonyl (Co-ASS) is an auspicious lead, which exhibits its anticancer activity mainly by inhibition of both cyclooxygenases (COX-1 and COX-2). Since COX-2 participates in carcinogenesis, a selective inhibition of that isoenzyme is aimed. To study if fluorination increases the COX-2/COX-1 inhibition ratio of the lead, substitution was respectively performed in the positions 3, 4, 5, and 6 of the aromatic moiety. The complexes 3/4/5F-Co-ASS and to a much lower extent also 6F-Co-ASS showed cytotoxic, antimetabolic, and apoptotic effects in COX-1/2-positive HT-29 and MDA-MB-231 cells and remarkably less activity in the COX-1/2-negative MCF-7 cell line. The metabolic activity in MCF-7 cells was even unaffected up to a concentration of 40 mu M. With exception of 6F-Co-ASS, the complexes strongly reduced the PGE(2) synthesis in HT-29 cells and all complexes inhibited COX-2 more effectively than COX-1 in an assay at isolated enzymes. These findings point to an interference in the COX cascade as part of the mode of antitumor action. The limited cellular effects of 6F-Co-ASS are related to its poor uptake as determined by HR CS AAS/MAS. Moreover, the cellular uptake studies confirm fluorination as beneficial tool for bioanalytical labeling. The higher quantification of fluorine by HR CS MAS makes this method about 5-fold more sensitive than HR CS AAS measuring cobalt. As a further positive result, 3/4/5/6-Co-ASS demonstrated high selectivity to tumor cells due to lack of antimetabolic activity against the non-tumorigenic bone marrow stromal cell line HS-5.

Here, we have established a new and simple synthetic approach to the pentacycloundecane containing cage oxazole unit in four steps. The synthesis begun with a cheap and readily available materials such as 2,5-dimethoxybenzaldehyde and endo-dicyclopentadiene. This approach relies on Van Leusen oxazole synthesis and [2+2] photocycloaddition as key steps. To the best of our knowledge, this is the first example of Cookson’s dione containing oxazole ring system. Some of these oxazole motifs are useful in bioorganic chemistry and our results are likely to draw the attention of medicinal chemists

HGF/c-Met signalling pathway plays an important role in the development of cancers. A series of 6,7-dimethoxy-4-anilinoquinolines possessing benzimidazole moiety were synthesised and identified as potent inhibitors of the tyrosine kinase c-Met. Their in vitro biological activities against three cancer cell lines (A549, MCF-7, and MKN-45) were also evaluated. Most of these compounds exhibited moderate to remarkable potency. Among them, compound 12n showed the most potent inhibitory activity against c-Met with IC50 value of 0.030 +/- 0.008 mu M and it also showed excellent anticancer activity against the tested cancer cell lines at low micromolar concentration. Molecular docking verified the results and revealed the possible binding mode of the most promising compound 12n into the ATP-binding site of c-Met kinase.

Rationale The halogenated derivatives of N-(2-methoxy)benzyl-2,5-dimethoxyphenethylamine (25-NBOMe) such as the 4-bromo analogue (25B-NBOMe) represent a new class of hallucinogenic or psychedelic drugs. The purpose of this study was to determine the role of the electron-donating groups (halogen and dimethoxy) in the pathway of decomposition for the distonic molecular radical cation in the electron ionization mass spectrometry (EI-MS) process of the trifluoroacetamide (TFA) derivatives. Methods The systematic removal of substituents from the 4-halogenated 2,5-dimethoxyphenethylamine portion of the N-dimethoxybenzyl NBOMe analogues allowed an evaluation of structural effects on the formation of major fragment ions in the EI-MS of the TFA derivatives. All six regioisomeric dimethoxybenzyl-substituted analogues (2,3-, 2,4-, 2,5-, 2,6-, 3,4- and 3,5-dimethoxy) for the four series of phenethyl aromatic ring substitution patterns were prepared, derivatized and analyzed via gas chromatography coupled with EI-MS. Results The analogues yield two unique radical cation fragments from the decomposition of the common distonic molecular radical cation. The substituted phenylethene radical cation (m/z 164) is the base peak or second most abundant ion in all six TFA-2,5-dimethoxyphenethylamine isomers. The dimethoxybenzyltrifloroacetamide radical cation (m/z 263) is the base peak or second most abundant ion in the 2- and 3-monomethoxyphenethylamine isomers. However, the 2- and 3-methoxyphenylethene radical cation (m/z 134) is among the five most abundant ions for each of these twelve isomers. Only one isomer in the phenethylamine series yields the corresponding unsubstituted phenylethene radical cation at m/z 104. Conclusions The decomposition of the hydrogen-rearranged distonic molecular radical cation favors formation of the dimethoxybenzyltrifloroacetamide (m/z 263) species for the less electron-rich phenethyl aromatic rings. The addition of electron-donating groups to the aromatic ring of the phenethyl group as in the NBOMe-type molecules shifts the decomposition of the common distonic molecular radical cation to favor the formation of the electron-rich substituted phenylethene radical cation.

A clean and highly efficient protocol for green synthesis of bis(indole)methanes and bis(pyrazolyl)methanes has been successfully achieved by using a naturally sourced bio-surfactant, chickpea leaf exudates (CLE), as a Bronsted acid-type catalyst. The reaction proceeds smoothly with CLE in alcoholic medium at 60 degrees C in a very short reaction time, and therefore it is a green, environmentally sound alternative to the existing protocols. In comparison to the reported conventional methods, this synthetic pathway complies with several key requirements of green chemistry principles such as avoiding the use of any toxic/hazardous catalyst and additives/promoters, the use of a biodegradable catalyst obtained from renewable resources, auxiliary solvent conditions, and reusability of the catalyst. Thus, the reported protocol offers an attractive option because of its ecological safety, straightforward work-up procedure and excellent values of green chemistry metrics as compared with other reported methods.

Despite the fact that significant advances in treatment of common cancers have been achieved over the years, orphan tumors still represent an important unmet medical need. Due to their complex multifactorial origin and limited number of cases, such pathologies often have very limited treatment options and poor prognosis. In the search for new anticancer agents, our group recently identifiedRC-106, a Sigma receptor modulator endowed with proteasome inhibition activity. This compound showed antiproliferative activity toward different cancer cell lines, among them glioblastoma (GB) and multiple myeloma (MM), two currently unmet medical conditions. In this work, we directed our efforts toward the exploration of chemical space aroundRC-106to identify new active compounds potentially useful in cancer treatment. Thanks to a combinatorial approach, we prepared 41 derivatives of the compound and evaluated their cytotoxic potential against MM and GB. Three novel potential anticancer agents have been identified.

Diflubenzuron (DFB) and fenuron (FEN) are benzoylurea and phenylurea pesticides, widely used in Senegal, that do not exhibit any natural fluorescence, but can be determined by means of photoinduced fluorescence (PIF) methods. Photodegradation of DFB and FEN yielded a number of fluorescent and non-fluorescent photoproducts. For both pesticides, at least 10 photoproducts were detected and identified by gas chromatography-mass spectrometry (GC/MS). To identify the formed fluorescent DFB and FEN photoproducts, their fluorescence spectra were compared with those of standard compounds, including phenol and p-hydroxyaniline.

Present work demonstrates synthesis and antibacterial property of new pyrazole derivatives. A series of new Curcumin based dihydropyrazoles has been synthesized with an objective to evaluate their antibacterial property. Dihydropyrazoles analogues were synthesized using Curcumin based chalcones and differently substituted phenylhydrazine derivatives. We used the previously designed Curcumin based chalconesto react with phenylhydrazine derivatives in ethanol in a catalyst free medium to afford new dihydropyrazole derivatives. Effect of substituent on reactivity was also studied. All the synthesized pyrazole analogues were characterized using proton and carbon NMR, Mass spectroscopy and IR techniques. Effect of substituent on reactivity was explained on the basis of electronic effect generated due to groups on phenyl ring. Presence of dd (double doublet) in proton NMR spectrum of Dihydropyrazoles was also explained due to presence of optically active carbon of pyrazole ring. The synthesized library was screened for their inhibitory activity against 4 different bacterial strains 1. E. Coli (ATCC 9637), 2. Pseudomonas aeruginosa (ATCC BAA-427), 3. Staphylococcus aureus (ATCC 25923) and 4. Klebsiella pneumonia (ATCC 27736). Out of all the compounds evaluated, the compounds that exhibited IC50 value greater than 50 mu M, were considered to be inactive. We established an important SAR based on the structure dependent inhibitory potential of screened dihydropyrazoles. Two compounds 4e and 4t having nitro and benzyl substitution respectively were showing the best inhibitory potential against Gram Positive bacterial strain Staphylococcus aureus with MIC value of 1.56 mu g/ml. Compounds having Chloro and Methoxy substitution were found to be less effective against screened bacterial strains. Compounds 4a and 4b were selective towards Staphylococcus aureus species with the MIC value of 1.56 mu g/ml for each. These pyrazole analogues were not showing inhibitory potential against other screened bacterial strains.

Aim: To design, synthesis and in vitro evaluation of 4-oxo-6-substituted phenyl-2-thioxo 1,2,3,4-tetrahydropyrimidine-5-carbonitrile derivatives as HIV integrase strand transfer inhibitors. Background: Human immunodeficiency virus-1 (HIV-1), a member of retroviridae family, is the primary causative agent of acquired immunodeficiency syndrome (AIDS). Three enzymes viz: integrase (IN), reverse transcriptase (RT) and protease play important role in its replication cycle. HIV-1 integrase is responsible for the incorporation of viral DNA into human chromosomal DNA by catalyzing two independent reactions, 3′-processing (3′-P) and strand transfer (ST), which are observed as the point of no-return in HIV infection. Objective: To develop inhibitors against HIV integrase strand transfer step. Methods: Our previous results indicated that tetrahydro pyrimidine-5-carboxamide derivatives are potent HIV-1 IN inhibitors (unpublished results from our laboratory). Taking clue from above studies and our own experience, we hypothesized 4-oxo-6-substituted phenyl-2-thioxo 1,2,3,4-tetrahydropyrimidine-5-carbonitrile analogues (14a to 14n) as inhibitors of HIV-1 Integrase strand transfer. Prototype compound 14 can be viewed as hybrid structure having characteristics of dihydropyrimidine derivatives 10-12 and tyrphostin 13. Results: A total of fourteen derivatives of 4-oxo-6-substituted phenyl-2-thioxo-1,2,3,4-tetrahydro-pyrimidine-5-carbonitrile (14a-14n) were synthesized and evaluated using HIV-1 Integrase Assay Kit (Xpressbio Life Science Products, USA). The percentage inhibition of all compounds was investigated at 10 mu M concentration and IC50 value of few highly active compounds was studied. The obtained results were validated by in silico molecular docking study using Glide (maestro version 9.3, Schrodinger suite) in extra precision (XP) mode. Conclusion: Fourteen 4-oxo-6-substituted phenyl-2-thioxo 1,2,3,4-tetrahydropyrimidine-5-carbonitrile analogues were synthesized and evaluated for HIV-1 IN inhibitory activity. Three compounds 14a, 14e, and 14h exhibited significant percentage inhibition of HIV-1 IN. There was good in vitro – in silico correlation. However, none of the derivative was active against HIV-1 and HIV-2 below their cytotoxic concentration. It needs to be seen whether these compounds can be explored further for their anti-HIV or cytotoxic potential.
