The effective and economically feasible tandem synthesis of gamma-valerolactone (GVL), a renowned bio-based platform molecule with great promising applications in the production of drop-in chemicals, liquid fuels and polymers, is significantly vital and challenging. Herein, we for the first time describe a direct and effective catalytic system based on ZrOCl2 center dot 8H(2)O capable of facilitating the one-pot one-step tandem synthesis of GVL from bio-based furfural or furfuryl alcohol in 2-propanol by integrating sequential transfer hydrogenation, ring-opening, and transfer hydrogenation-cyclization reactions. A maximum GVL yield of 63.3% and 52.1% was achieved from furfuryl alcohol and furfural at 200 degrees C, respectively. The synergistic effect of [ZrO(OH)(2)](n)center dot xH(2)O species and Bronsted acid species H+, derived from in situ hydrolysis of ZrOCl2 center dot 8H(2)O, is accountable for its remarkable catalytic performance. Moreover, calcination of the leftover solid after tandem synthesis of GVL could fabricate a hollow microrod ZrO2 material, in which the formation of a microrod morphology and hollow structure was probably attributed to the electrostatic repulsion forces among particles in the alcohol solution and removal of generated humins/coke during the reactions within collected solids via calcination, respectively. Importantly, hollow microrod ZrO2 innovatively featuring a high BET surface area, a large amount of acid-base sites and facile active-site accessibility thereby exhibited a superior performance in the catalytic transfer hydrogenation of biomass-derived aldehydes or ketones to ZrO2 prepared by the precipitation method.

N-doped TiO2, denoted as T_400, was prepared simply by the facile thermal hydrolysis of TiOSO4 using NH4OH as both a precipitating agent and a nitrogen source. Compared to TiO2 without nitrogen doping, T_400 provides superior photocatalytic activity toward the selective oxidation of benzyl alcohol and benzylamine under visible light irradiation, with > 85 % conversion and > 95 % selectivity to benzaldehyde and N-benzylidenebenzylamine products, respectively. The increased photoactivity of T_400 is ascribed to enhanced visible-light absorption and efficient photogenerated charge transfer and separation as supported by UV-vis DRS, photoelectrochemical and VB-XPS results. The catalyst can tolerate the presence of substituent groups in benzyl alcohol and benzelamine molecules as > 80 % conversion and > 95 % selectivity are still achieved, which expands the scope of substrates and catalyst utilization. Band energy level of N-doped TiO2 compared to that of undoped TiO2 is determined using Mott-Schottky and UV-vis DRS measurements. Possible mechanisms for the formation of benzaldehyde and N-benzylidenebenzylamine over N-doped TiO2 are proposed. This work presents a simple synthesis of N-doped TiO2, using a low-cost and easily handled inorganic titanium salt instead of air/moisture-sensitive alkoxide precursors and reveals its potential application toward photocatalytic synthesis of organic fine chemicals under visible light.

In this report, SO3H-functionalized Carbon nanoparticles (Pine-SO3H) with high acid density have been synthesized by the thermal treatment of sulfuric acid with Pine-Cone as carbon-based at 180 degrees C in a sealed autoclave in a one-step procedure. The resulted Nanocatalyst was characterized by FT-IR, TGA, XRD, FE-SEM and elemental analysis (EA). The result of characterization was shown that the carbon-based acid is amorphous with polycyclic aromatic carbon sheets attached plentiful -OH, -COOH, and -SO3H groups. The catalytic activities of Pine-SO3H was investigated in the highly efficient synthesis of pyrano[2,3-c] pyrazole, amino-benzochromenes, amidoalkyl naphthol and 5-arylidene-2,4-thiazolidinedione derivatives. The application of Pine-SO3H in the synthesis offers several advantages such as simple procedure with an easy work-up, recoverable catalyst, mild condition, eco-friendliness, excellent yields, short reaction times and use of an inexpensive catalyst.

A series of novel dihydropyranoindole derivatives containing sulphonamide group were designed, synthesized and evaluated for in-vitro anti-cholinesterase activity. The result showed that all the compounds exhibited potent acetylcholinesterase (AChE) activity (IC50 = 0.41-8.79 mu M) while demonstrated moderate to good activity for butyrylcholinesterase (BuChE) (IC50 = 1.17-30.17 mu M). The tested compounds exhibited selectivity towards AChE over BuChE. Compound 5o was most potent towards both AChE (IC50 = 0.41 mu M) and BuChE (IC50 = 1.17 mu M) when compared to standard galantamine and rivastigmine. Enzyme kinetics and molecular docking studies revealed that compound 5o shows mixed type inhibition and binds to peripheral anionic site (PAS) and the catalytic sites (CAS) of both the enzymes. Furthermore, cell viability studies were also performed against N2a cells along with neuroprotection studies against H2O2 in the same cell line. Antioxidant studies using DPPH radical and H2O2 were also performed which revealed that all compounds possessed some antioxidant activity. Also, DNA damage protection assay for compound 5o was performed implying that compound 5o was protective in nature. ADME studies were also performed which demonstrated good pharmacokinetics. These findings indicated that dihydropyranoindole derivatives could be possible drug lead in the search for new multifunctional AD drugs.

The rising demand for picrosides commercially and over-exploitation ofPicrorhiza kurroafrom natural habitat has to initiate alternative strategies for sustainable production of metabolites. In the present research, wild leaf explant ofP. kurroawas used to produce friable callus under different culture condition, i.e., dark and light with two temperature variants (15 degrees C and 25 degrees C). Afterward, callus cell lines were screened based on growth biomass and metabolites content accumulation. The results revealed, maximum callus growth index along with antioxidant potential (IC50-40.88 mu g/mL) and total phenol content (41.35 mu g/mg) were observed under dark 25 degrees C. However, under light 15 degrees C, highest accumulation of picroside II (0.58 mu g/mg), cinnamic acid (0.15 mu g/mg),p-hydroxy acetophenone (0.30 mu g/mg), total flavonoids (77.30 mu g/mg), nitrogen (7.06%), carbohydrates (18.03%), and protein (44.12%) were detected. Major reported metabolite in callus was picroside I (1.63 mu g/mg) under dark 15 degrees C. For the first time, picroside III content (range 0.15-0.56 mu g/mg) was also detected and quantified in leaf-derived calli. Expression profiling of picroside biosynthetic pathway genes showed a positive correlation with the observed metabolites. Furthermore, an optimized protocol of metabolites enriched callus biomass could be used as potential strategy for sustainable production of picrosides at commercial scale.

17beta-Hydroxysteroid dehydrogenase type 10 (17 beta-HSD10) is the only mitochondrial member of 17 beta-HSD family. This enzyme can oxidize estradiol (E2) into estrone (E1), thus reducing concentration of this neuroprotective steroid. Since 17 beta-HSD10 possesses properties that suggest a possible role in Alzheimer’s disease, its inhibition appears to be a therapeutic strategy. After we identified the androsterone (ADT) derivative 1 as a first steroidal inhibitor of 17 beta-HSD10, new analogs were synthesized to increase the metabolic stability, to improve the selectivity of inhibition over 17 beta-HSD3 and to optimize the inhibitory potency. From six D-ring derivatives of 1 (17-C = O), two compounds (17 beta-H/17 alpha-OH and 17 beta-OH/17aC CH) were more metabolically stable and did not inhibit the 17 beta-HSD3. Moreover, solid phase synthesis was used to extend the molecular diversity on the 3b-piperazinylmethyl group of the steroid base core. Eight over 120 new derivatives were more potent inhibitors than 1 for the transformation of E2 to E1, with the 4-(4-trifluoromethyl-3-methoxybenzyl)piperazin-1-ylmethyl-ADT (D-3,7) being 16 times more potent (IC50 = 0.14 mM). Finally, D-ring modification of D-3,7 provided 17 beta-OH/17 alpha-C CH derivative 25 and 17 beta-H/17 alpha-OH derivative 26, which were more potent inhibitor than 1 (1.8 and 2.4 times, respectively).
