Abstract
A green approach has been developed for the synthesis of a series of benzylidene acrylate 3(a-p) from differently substituted aromatic/heterocyclic aldehydes and ethyl cyanoacetate in excellent yields (90-98%), and employing silica bonded N-(Propylcarbamoyl)sulfamic acid as a recyclable catalyst under solvent-free condition. The molecular structure of compounds 3b, 3d and 3i were well supported by single-crystal X-ray crystallographic analysis. The present protocol bears wide substrate tolerance and is believed to be more practical, efficient, eco-friendly, and compatible as compared to existing methods. In-silico approaches were implemented to find the biochemical and physiological effects, toxicity, and biological profiles of the synthesized compounds to determine the expected biological nature and confirm a drug-like compound. A molecular docking study of the expected biologically active compound was performed to know the hypothetically binding mode with the receptor. Also, reverse docking is applied to recognize receptors from unknown protein targets for drug-like compounds to explain poly-pharmacology and binding postures with different receptors.

Abstract
Understanding the targeted cellular uptake of nanomaterials is an essential step to engineer and program functional and effective biomedical devices. In this respect, the targeting and ultrafast uptake of zeolite nanocrystals functionalized with Cetuximab antibodies (Ctxb) by cells overexpressing the epidermal growth factor receptor are described here. Biochemical assays show that the cellular uptake of the bioconjugate in the targeted cancer cells already begins 15 min after incubation, at a rate around tenfold faster than that observed in the negative control cells. These findings further show the role of Ctxb exposed at the surfaces of the zeolite nanocrystals in mediating the targeted and rapid cellular uptake. By using temperature and pharmacological inhibitors as modulators of the internalization pathways, the results univocally suggest a dissipative uptake mechanism of these nanomaterials, which seems to occur using different internalization pathways, according to the targeting properties of these nanocrystals. Owing to the ultrafast uptake process, harmless for the cell viability, these results further pave the way for the design of novel theranostic tools based on nanozeolites.

Combined Effects of Vincristine and Quercetin in Reducing Isoproterenol-Induced Cardiac Necrosis in Rats. Cardiovasc Toxicol 2016; 15:291-9.

Abstract
Combined effects of vincristine and quercetin in the regulation of isoproterenol (ISO)-induced cardiac necrosis have been evaluated in rats. ISO administration (100 mg/kg, s.c., for two consecutive days) increased the levels of serum creatine kinase-MB (CK-MB), lactate dehydrogenase (LDH), glutamate pyruvate transaminase (SGPT) and cardiac troponin (cTnT) as well as cardiac lipid peroxidation products (malondialdehyde and lipid hydroperoxides). However, it reduced the activities of superoxide dismutase (SOD), catalase and the glutathione peroxidase and the level of reduced glutathione. It also increased the heart rate and ST-segment elevation in ECG. Pretreatment of vincristine (25 μg/kg) or quercetin (10 mg/kg) alone for 2 weeks ameliorated these cardiotoxic effects partially. However, treatment of both vincristine and quercetin for a similar period reduced the serum CK-MB, LDH, SGPT and cTnT levels near to normal levels in ISO-treated rats. Concomitantly, the test drugs improved the status of antioxidants and decreased the cardiac lipid peroxidation products. Combined treatment of both the drugs also restored the pathological electrocardiographic patterns and reduced the area of myocardial necrosis. Histopathology of heart in ISO-administered rats that received both vincristine and quercetin showed nearly normal myocardium with very little inflammatory infiltration. In conclusion, the present finding appears to be the first one, suggesting a better protection of cardiac tissues by combined treatment of vincristine and quercetin in isoproterenol-induced cardiac toxicity.

Abstract
A series of N-((1-benzyl-1H-1,2,3-triazol-4-yl)methyl)nicotinamides (4) was synthesized and tested for their anticancer activity against a panel of 60 human cancer cell lines. Some of the representative compounds such as 4a, 4b, 4f, 4g, 4i and 4t were selected for the five dose study and amongst them 4g and 4i displayed significant anticancer activity with GI50 values ranging from 0.25 to 8.34 and 1.42 to 5.86μM, respectively. Cell cycle analysis revealed that these compounds induced cell cycle arrest at G2/M phase in MCF-7 cells. The most active compound in this series 4g also inhibited tubulin polymerization with IC50 value 1.93μM superior to that of E7010. Moreover, assay to investigate the effect on caspase-9, Hoechst staining and DNA fragmentation analysis suggested that these compounds induced cell death by apoptosis. Docking experiments showed that they interact and bind efficiently with tubulin protein. Overall, the results demonstrate that N-((1-benzyl-1H-1,2,3-triazol-4-yl)methyl)nicotinamide scaffold possess anticancer property by inhibiting the tubulin polymerization.

Abstract
A series of eight novel podophyllotoxin derivatives were designed, synthesized and evaluated for biological activities. The antiproliferative activities were tested against a panel of human cancer cell lines (K562, SGC, Hela and HepG) and the inhibition of tubulin polymerization was also evaluated. Compound 8e displayed significant antiproliferative activities for all four cell lines and strong levels of tubulin polymerization inhibition effect. Combined with cell apoptosis and cell cycle analysis, it demonstrated that compound 3e that effectively interfere with tubulin dynamics prevent mitosis in cancer cells, leading to cell cycle arrest and, eventually dose dependent apoptosis. All experimental measurements were also supported by molecular docking simulations of colchicine binding site, which revealed the governing forces for the binding behavior and a good relationship with anti-tubulin activity and antiproliferative activities. The synthesis and biological studies provided an interesting new class of antitubulin agents for development of lead compounds and also a direction for further structure modification to obtain more potent anti-cancer drugs.

Abstract
A novel series of phenylimino-10H-anthracen-9-ones and 9-(phenylhydrazone)-9,10-anthracenediones were synthesized and evaluated for interaction with tubulin and for cytotoxicity against a panel of human tumor cell lines. The 10-(3-hydroxy-4-methoxy-phenylimino)-10H-anthracen-9-one 15h and its dichloro analog 16b were identified as potent inhibitors of tumor cell growth (16b, IC(50) K562 0.11 μM), including multidrug resistant phenotypes. Compound 15h had excellent activity as an inhibitor of tubulin polymerization. Concentration-dependent cell cycle analyzes by flow cytometry confirmed that KB/HeLa cells treated by 15h and 16b were arrested in the G2/M phases of the cell cycle. In competition experiments, 15h strongly displaced radiolabeled colchicine from its binding site on tubulin, showing IC(50) values similar to that of colchicine. The results obtained demonstrate that the antiproliferative activity is related to the inhibition of tubulin polymerization.

Abstract
Tubulin is a heterodimeric protein whose self assembly leads to the formation of protofilaments and of more complex structures called microtubules, key components of the cytoskeleton which have a fundamental role in the cell division process. Due to its biological function, tubulin is the target of many antitumoral molecules that exert their action on proliferating tumoral cells. Among these drugs, vinblastine has been widely used in therapy for a long time, albeit its mechanism of interaction with tubulin has remained elusive until recently. Vinblastine acts as a microtubule destabilizing agent and induces the formation of curved or ring-shaped tubulin polymers instead of linear protofilaments in vitro. In this paper we compare, using molecular dynamics simulations and free energy calculations, the network of interactions that allow the assembly of model linear protofilaments with those present in curved tubulin polymers complexed with vinblastine. It is shown that vinblastine, wedging between tubulin heterodimers, actually mediates part of the interactions between them and acts by crosslinking the two proteins, leading to the observed curved polymers rather than to their disassembly.
