This chapter focuses on the photochemical isomerization of penta-atomic heterocyclic compounds. The description of the photochemical behavior of pentaatomic heterocyclic compounds is confused. Five mechanisms are invoked to justify the observed behaviors: (1) the ring contraction-ring expansion route (RCRE), (2) the internal cyclization-isomerization route (ICI), (3) the van Tamelen-Whitesides general mechanism (VTW), (4) the Zwitterion-tricycle route (ZT), (5) the fragmentation-readdition route (FR). The direct irradiation of a penta-atomic heterocycle leads to the formation of a singlet-excited state. This excited state can interconvert into the corresponding triplet state or into the corresponding Dewar isomer. The Dewar isomer is the origin of the formation of isomeric heterocyclic derivatives. The excited triplet state obtained via intersystem crossing from the corresponding excited singlet state or via a sensitized reaction can evolve to give a biradical intermediate. This biradical intermediate can be converted into decomposition products or into ring-contraction products. The ring-contraction products can be irradiated under the reaction conditions used to give isomeric heterocyclic derivatives.

The synthesis of (isoxazol-4-ylmethyl)triphenylphosphonium salts derived from 5-alkyl- and 5-aryl-3-methylisoxazoles has been carried out. This method involves the preparation of several 4-(chloromethyl)isoxazoles which are suitable precusors for these phosphonium salts. The phosphonium salts were completely characterized by spectroscopic methods and were obtained in very good to quantitative yields.

A series of novel 5-benzylidene-2,4-thiazolidinediones were designed as inhibitors of angiogenesis targeting VEGFR-2. In docking study, molecules showed similar way of binding with VEGFR-2 as that of the co-crystallized ligand. Compounds were then synthesized, purified and characterized by spectroscopic techniques. Compounds 3f and 3i were found to be most active in the series showing good inhibition of angiogenesis in both CAM and in zebrafish embryo assays. Compound 3i also exhibited IC50 of 0.5 muM against VEGFR-2.

Attempts to establish degrees of aromaticity in molecules are legion. In the present study, we begin with a fictitious fragment arising from only those atoms contributing to the aromatic ring and having a force field projected from the original system. For example, in benzene, we adopt a fictitious C6 fragment with a force field projected from the full benzene force field. When one bond or angle is stretched and kept fixed, followed by a partial optimization for all other internal coordinates, structures change from their respective equilibria. These changes are the responses of all other internal coordinates for constraining the bond or angle by unit displacements and relaxing the forces on all other internal coordinates. The “interaction coordinate” derived from the redundant internal coordinate compliance constants measures how a bond (its electron density) responds for constrained optimization when another bond or angle is stretched by a specified unit (its electron density is perturbed by a finite amount). The sum of interaction coordinates (responses) of all bonded neighbors for all internal coordinates of the fictitious fragment is a measure of the strength of the sigma and pi electron interactions leading to aromatic stability. This sum, based on interaction coordinates, appears to be successful as an aromaticity index for a range of chemical systems. Since the concept involves analyzing a fragment rather than the whole molecule, this idea is more general and is likely to lead to new insights.

This study deals with synthesis of a new set of benzofuran and 5H-furo[3,2-g]chromone linked various heterocyclic functionalities using concise synthetic approaches aiming to gain new antiproliferative candidates against MCF-7 breast cancer cells of p38alpha MAP kinase inhibiting activity. The biological data proved the significant sensitivity of breast cancer cell lines MCF-7 towards most of the prepared compounds in comparison with doxorubicin. In addition, compounds IIa,b, Va,b, VIa,b, VIIa,b, VIIIa,b, XIc showed significant in vitro p38alpha MAPK inhibiting potency comparable to the reference standard SB203580. Cell cycle analysis and apoptosis detection data demonstrated that compound VIa induced G2/M phase arrest and apoptosis in MCF-7 cancer cells, in addition to its activation of the caspases-9 and -3. Gold molecular docking studies rationalized the highly acceptable correlation between the calculated docking scores of fitness and the biological data of p38alpha MAP kinase inhibition. The newly prepared benzofuran and 5H-furo[3,2-g]chromone derivatives might be considered as new promising nuclei in anti-breast cancer chemotherapeutics for further functionalization, optimization and in-depth biological studies.

Gastric cancer is one of the most common malignancies and a leading cause of cancer death worldwide. The prognosis of stomach cancer is generally poor as this cancer is not very sensitive to commonly used chemotherapies. Epigenetic modifications play a key role in gastric cancer and contribute to the development and progression of this malignancy. In order to explore new treatment options in this target area we have screened a library of epigenetic inhibitors against gastric cancer cell lines and identified inhibitors for the BET family of bromodomains as potent inhibitors of gastric cancer cell proliferations. Here we show that both the pan-BET inhibitor (+)-JQ1 as well as a newly developed specific isoxazole inhibitor, PNZ5, showed potent inhibition of gastric cancer cell growth. Intriguingly, we found differences in the antiproliferative response between gastric cancer cells tested derived from Brazilian patients as compared to those from Asian patients, the latter being largely resistant to BET inhibition. As BET inhibitors are entering clinical trials these findings provide the first starting point for future therapies targeting gastric cancer.

This chapter focuses on transition metal-catalyzed reactions using isoxazoles, anthranils and 1,2-benzisoxazoles. Selected topics include the use of these nitroxy aromatic species in (i) metal-catalyzed annulations of alkynes (ii) catalytic reactions with metal carbenes and (iii) catalytic aminations of aryl C[sbnd]H bonds. In the alkyne annulation, these aromatic species typically generate alpha-imino gold carbenes that can further be elaborated to form various azacyclic compounds via a suitable functionality on alkynes, whereas with metal carbenes prototypical reactivity involves their imination. For Rh(I)-catalyzed aryl C[sbnd]H aminations, these N[sbnd]O aromatic species react with Rh metalocycles to cleave their N[sbnd]O bond and form a Rh[sbnd]N bond, furnishing Ar[sbnd]N bond formation. The large family of azacyclic products accessible from these three reactions further highlight their synthetic utility.
