Extending the applications of Photoremovable Protecting Groups (PPGs) to cage phenols has generally met with unusually complex PPG byproducts. In this study, we demonstrate that thep-hydroxyphenacyl (pHP) cage for both simple and complex phenolics, including tyrosine, dispenses free phenols. With the simpler unsubstituted phenols, the reaction is governed by their Bronsted Leaving Group ability. On the other hand, the byproducts of the cage vary with these phenols. For the more acidic phenols the cage byproduct follows the Favorskii rearrangement to formp-hydroxyphenylacetic acid whereas for the weaker phenols other reactions such as reduction and hydrolysis begin to emerge. When the photolysis is conducted in octa acid (OA) containers, non-Favorskii, unrearranged fragments of the cage and other byproducts arise.

A Ta2O5-anchored-piperidine-4-carboxylic acid (PPCA) nanoparticle has been synthesized and characterized. It was then used as a highly effective nanocatalyst for the synthesis of quinolin-2(1H)-one derivatives through C-O bond functionalization. The special advantage of this heterogeneous solid catalyst is the reusability of the catalyst for up to five cycles without any noticeable reduction in product yields. In comparison, healthy reaction profiles, wide substrate scope, excellent yields and easy workup conditions are the notable highlights of this approach. All the compounds were tested for their anticancer activity against MCF-7 (human breast), HepG2 (human liver), HCT116 (human colorectal), and PC-3 (human prostate) cancer cell lines with the MTT assay. All the compounds were shown to have moderate to good inhibitory effects on tested cancer cell lines. Besides, compounds 5b, 5c and 5d showed good selectivity against epidermal growth factor receptor-tyrosine kinase (EGFR-TK). Molecular docking results showed that active compounds showed a good affinity towards EGFR kinase (PDB ID: 6V6O) by forming two hydrogen bonds with Cys-797 and Tyr-801. All the compounds were screened for computational ADMET and Lipinski analysis.

Lantana camara (L.) is employed by several ethnical groups to treat numerous diseases. Although there are no ethnomedical reports on its use against leishmaniasis, organic extracts prepared from L. camara were shown to display leishmanicidal activity. In the present study, we carried out a bioassay-guided fractionation of the dichloromethane extract from Mexican L. camara in order to identify the compounds responsible for the leishmanicidal activity. Eighteen chromatographic fractions (FI-FXVIII) were evaluated in vitro against Leishmania mexicana and L. amazonensis. FII, FX, FXI, FXV, and FXVI showed significant activity against both Leishmania strains, the most potent of which was FXV. Eicosane (1), squalene (2), -ionone (3), caryophyllene oxide (4), -caryophyllene (5), hexanoic acid (6), tiglic acid (7), a mixture of lantanilic (8) and camaric (9) acids, and lantadene B (10) were identified and obtained from the active fractions and evaluated for their leishmanicidal activity. The mixture of lantanilic (8) and camaric (9) acids (79%/21%) was the most potent one (half maximal inhibitory concentration (IC50) = 12.02 +/- 0.36 M). This study indicates that this cultivar of L. camara has high potential for the development of phytomedicines or as a source of natural products, which might represent lead compounds for the design of new drugs against leishmaniasis.

In the present work, we report the design and fabrication of a copper-containing ionic liquid supported magnetic nanocatalyst via a convenient and straightforward synthetic approach for the formation of 2-phenylquinazolin-4(3H)-ones using o-aminobenzamide and benzaldehydes as the reaction partners. The successful formation and properties of the as-prepared catalyst have been thoroughly investigated using diverse physico-chemical techniques including FT-IR, XRD, FE-SEM, TEM, ICP, VSM, BET and TGA. Using this nanocatalytic system, a variety of 2-phenylquinazolin-4(3H)-ones are synthesized in excellent yields with operational ease and short reaction times in an environmentally preferable solvent under open air and without using any external oxidizing agent. Besides, the catalyst possessed facile magnetic recoverability and remarkable reusability for six consecutive runs without any appreciable decrease in the catalytic efficiency.

Compared with the ever-growing list of nonprochiral nucleophiles in Ir-catalyzed asymmetric allylic substitution reactions, prochiral nucleophiles are less studied. We present a new prochiral nucleophile, namely, deconjugated butyrolactam, for Ir-catalyzed asymmetric allylic alkylation (AAA). This reaction provides access to a-allyl deconjugated butyrolactams with a moderate to good dr and an excellent er. This is the first AAA reaction of deconjugated butyrolactams. Allyl transposition through Cope rearrangement appears to proceed stereospecifically to form.-allyl conjugated butyrolactams.

A heterogeneous organic-inorganic hybrid durable nanocatalyst gamma-Al2O3@Silane-TMG was prepared by covalently functionalization of nano-gamma-Al2O3 through anchored 3-chloropropyl- trimethoxysilane with 1,1,3,3-tetramethylguanidine (TMG). The structure of the catalyst was characterized by various techniques including FT-IR, XRD, SEM, EDX and TGA analyses. The synthesized nanocatalyst was successfully used in an efficient and green four-component synthesis of pyrazolopyranopyrimidine derivatives using ethyl acetoacetate, hydrazine hydrate, arylaldehydes and barbituric acid (or thiobarbituric acid) in H2O at 40 oC. This practical method produced the desired products at reduced reaction times (10-25 min) and high to excellent yields (85-98%). The main advantages of this practical method are the use of heterogeneous basic nanocatalyst, simple work-up procedure with no need to chromatographic purification, affording highly selective conversion and recyclability of the catalyst which could be used in 5 cycles with only a small decrease in its activity.

New acetamide (IV a-e) and 1,3-thiazolidinone derivatives (VII a-e) were designed, synthesized and assessed for their cytotoxic activity against MCF-7 and A549 cell lines along with their lead compounds (erlotinib and gefitinib). The newly designed compounds were prepared according to the adopted procedures in schemes 1 and 2 from their quinazolinone parents. 3D QSAR pharmacophore and docking molecular modeling protocols were conducted using Discovery Studio program, beside a full biological assay for these compounds. The cytotoxicity evaluation demonstrated that compounds IVb, IVc, VIIa, VIIb, VIId exhibited potent cytotoxic activities against both MCF-7 and A549 cell lines. Moreover, the molecular modeling studies corroborated to the affinity of the compounds towards EGFR. Consequently, these five compounds were then screened for their EGFR inhibition and evaluated as well for their toxicity to normal cells, which revealed that the acetamide derivative IVc and the thiazolidinone derivative VIIa were the most potent and least toxic. DNA flow cytometry analysis was conducted for compounds IVc and VIIa, which indicated that they both induced arrest at G2/M phase of the cell cycle.

Essential oils extracted from herbs have been utilized in food and medicine on the account of their increasing physicochemical characteristics. This present study aimed to investigate the phytochemical components, antiinflammatory, cytotoxic, anti-microbial and anti-oxidant activities of essential oils from Pogostemon cablin (P. cablin), Angelica dahurica (A. dahurica) and Myristica fragrans (M. fragrans), all belong to medicine food homology herbs. Approximately 107 components were identified by gas chromatography mass spectrometry (GC-MS) from these essential oils. The main compounds of P. cablin essential oils (PCEOs) were patchouli alcohol (27.72%), alpha-buaiacene (17.94%) and alpha-guaiene (14.15%); in A. dahurica essential oils (ADEOs) were anethole (24.91%) and cinnamaldehyde (18.35%); and in M. fragrans essential oils (MFEOs) were (1S)-(-)-alpha-pinene (23.39%), alpha-terpineol (18.60%) and caryophyllene (10.34%). These essential oils were found to have strong antiinflammatory activities through decreasing the production of cyclooxygenase-2 (COX-2), interleukin-6 (IL-6), nuclear factor-kappa B p65 (P65) and tumor necrosis factor-alpha (TNF-alpha). These essential oils also had significant anti-bacterial activities against both Gram-negative and Gram-positive strains and anti-fungal activities. Moreover, effective anti-oxidant properties of three essential oils were estimated (0.001962%-0.19%). The study also explored the effect of these essential oils on the survival of Brain microglia (BV2) microglial cells (IC50 = 145.50-281.52 mu g/mL). Based on these bioactivities, these essential oils could be used as food additives, fragrances, cosmetics and health products.

The direct synthesis of amides and nitriles from readily available aldehyde precursors provides access to functional groups of major synthetic utility. To date, most reliable catalytic methods have typically been optimized to supply one product exclusively. Herein, we describe an approach centered on an operationally simple iron-based system that, depending on the reaction conditions, selectively addresses either the C=O or C-H bond of aldehydes. This way, two divergent reaction pathways can be opened to furnish both products in high yields and selectivities under mild reaction conditions. The catalyst system takes advantage of iron’s dual reactivity capable of acting as (1) a Lewis acid and (2) a nitrene transfer platform to govern the aldehyde building block. The present transformation offers a rare control over the selectivity on the basis of the iron system’s ionic nature. This approach expands the repertoire of protocols for amide and nitrile synthesis and shows that fine adjustments of the catalyst system’s molecular environment can supply control over bond activation processes, thus providing easy access to various products from primary building blocks.

4-Hydroxy-3-methyl-2(1H)-quinolone (1), a molecule known for a long time and recently discovered from a Brassicaceae plant Isatis tinctoria without providing sufficient evidence to support the structure, was isolated from a fermentation extract of Burkholderia sp. 3Y-MMP isolated from a soil by a Zn2+ enrichment culture. Detailed spectroscopic analyses by MS and NMR, combined with C-13 chemical shift comparison with literature values of the related compounds and a synthetic preparation of 1, allowed its first full NMR characterization and identification of 2-quinolone but not 2-quinolinol (2) as the preferred tautomer for this heterocyclic system. While the metal-chelating activity was negligible, compound 1 at 10 mu M, a concentration lower than that in liquid production cultures, quenched hydroxy radical-induced chemiluminescence emitted by luminol by 86%. Because some Burkholderia species are pathogenic to plants and animals, the above result suggests that 1 is a potential antioxidant to counteract reactive oxygen species-based immune response in the host organisms.
