Several hundred (396) compounds from New Zealand flora with medicinal properties were analyzed for their physicochemical properties. It was found that approximately 10% fulfilled all the requirements to be considered to be lead-like, over half of the compounds were deemed to be in the drug-like space and approximate to 75% were in the known drug space. These results indicate the presence of a significant proportion of compounds that are of particular interest to pursue as potential lead compounds or therapeutics. Additionally, compound classes were analyzed separatelymost carbonyl-containing compounds (aldehydes, ketones, esters and lactones), along with phenols were the most lead-like compounds, which also displayed very good proportions in the drug-like and known drug space. The information presented herein can be harnessed and utilized in future work, through focussing on the compounds and compound classes that exhibit high-levels of lead-likeness for further development.

In an attempt to synthesise new tyrosinase inhibitors, we designed and synthesised a series of chalcone-hydroxypyridinone hybrids as potential tyrosinase inhibitors adopting strategic modifications of kojic acid. All the newly synthesised compounds were characterised by NMR and mass spectrometry. Initial screening of the target compounds demonstrated that compounds1a,1d, and1nhad relatively strong inhibitory activities against tyrosinase monophenolase, with IC(50)values of 3.07 +/- 0.85, 2.25 +/- 0.8 and 2.75 +/- 1.19 mu M, respectively. The inhibitory activity against monophenolase was 6- to 8-fold higher than that of kojic acid. Compounds1a,1d, and1nalso showed inhibition of diphenolase, with IC(50)values of 17.05 +/- 0.07, 11.70 +/- 0.03 and 19.3 +/- 0.28 mu M, respectively. The inhibition kinetics of diphenolase indicates that compounds1aand1dinduce reversible inhibition on tyrosinase. Finally, we found that copper coordination should be one of the important inhibitory mechanism of these compounds in tyrosinase.

The synthesis of chiral unsaturated gamma-lactams is reported featuring a highly enantioselective palladium-catalyzed asymmetric allylic alkylation of alpha,gamma-disubstituted 2-silyloxypyrroles. This method allows a straightforward access to optically active gamma-lactams bearing an alpha-quaternary stereogenic center in high yields (up to 93%), high regioselectivities (up to >20:1), and excellent enantioselectivities (up to 95% ee). To further demonstrate the synthetic utility of the method, the resulting allylated products were converted to various versatile chiral building blocks, such as pyrrolidines and pyrrolidinones.

In many metal catalyses, the traditional strategy of removing chloride ions is to add silver salts via anion exchange to obtain highly active catalysts. Herein, we reported an alternative strategy of removing chloride anions from ruthenium trichloride using an organic [P+-N-] zwitterionic compound via multiple hydrogen bond interactions. The resultant organic-metal hybrid catalytic system has successfully been applied to the aerobic oxidation of alcohols, tetrahydroquinolines, and indolines under mild conditions. The performance of zwitterion is far superior to that of many other common Lewis bases or Bronsted bases. Mechanistic studies revealed that the zwitterion triggers the dissociation of chloride from ruthenium trichloride via nonclassical hydrogen bond interaction. Preliminary studies show that the zwitterion is applicable to catalytic transfer semi-hydrogenation.

A divergent strategy for the facile preparation of various enantioenriched phenylthio-substituted lactones was developed based on Lewis base/Bronsted acid co-catalyzed thiolation of homoallylic acids. The acid-controlled regiodivergent cyclization (6-endo vs. 5-exo) and acid-mediated stereoselective rearrangement of phenylthio-substituted lactones were explored. Experimental and computational studies were performed to clarify the origins of the regioselectivity and enantioselectivity. The calculation results suggest that C-O and C-S bond formation might occur simultaneously, without formation of a commonly supposed catalyst-coordinated thiiranium ion intermediate and the potential pi-pi stacking between substrate and SPh as an important factor in the enantio-determining step. Finally, this methodology was applied in the rapid syntheses of the bioactive natural products (+)-ricciocarpin A and (R)-dodecan-4-olide.

The use of the unprecedented annulating reagents methyl N-(tert-butylsulfinyl)-4-chlorobutanimidate and methyl N-(tert-butylsulfinyl)-5-bromopentanimidate enables the diastereoselective preparation of 5- and 6-membered carbocycles bearing three contiguous stereocenters. These synthons undergo cycloaddition with a variety of Michael acceptors to form cyclopentane/cyclohexane rings with excellent stereochemical control, generating only one of the eight possible diastereomers. This novel methodology has enabled the highly enantioselective and high yielding synthesis of novel chemotypes of pharmacological relevance.

In the present work, coumarin based pyrazolines (7a-g) have been synthesized and investigated for their in vitro and in vivo anti-inflammatory potential. Amongst the synthesized compounds, compounds 7a, 7d and 7f exhibited significant in vitro anti-inflammatory activity as compared to the standard etoricoxib. Keeping this in mind, in vivo investigations were carried out via carrageenan induced inflammation and acetic acid induced writhing models in male Wistar rats and compound 7a was found to possess appreciable anti-inflammatory and analgesic potential. The mode of action of compound 7a was also investigated by using substance P as the biomarker, which shows promising results. Further, the selectivity of the most active compound 7a against the cyclooxygenase enzyme was supported by molecular docking studies which reveal that compound 7a has greater binding affinity towards COX-2 over COX-1 and 5-LOX enzymes. In silico ADME analysis of compound 7a confirms the drug-like characteristics and the in vivo acute toxicity study showed the safety of the compound even up to a 2000 mg kg(-1) dose. Thus, compound 7a was identified as an effective anti-inflammatory agent, and can be explored for further analgesic/anti-inflammatory drug design and development.

The present study was planned to apply the nanotechnology to therapeutically proven flavonoid-rich fraction for obtaining a formulation with enhanced antihyperglycemic activity. The leaves were extracted in aqueous methanol and fractionated to yield a flavonoid-rich fraction. This fraction was formulated into an aqueous nanosuspension using PVA through the nanoprecipitation method. The developed formulations were characterized for physical parameters and optimum nanosuspension was evaluated against type 2 diabetes in high-fat diet-fed, streptozotocin-induced diabetic animals. The pharmacokinetic parameter and histopathology were assessed to determine the kinetic profile and tissue architectures post oral administration of selected nano suspension. The selected nanosuspension was also studied for stability under accelerated conditions. Flavonoidrich fraction was obtained using Kupchan partitioning. The developed nanosuspension PG-EA-NS-B showed optimum physical parameters. In hyperglycemia induced by streptozotocin, in high-fat diet-fed rats, it effectively restores the normal level of blood glucose in the first hour. The effects were comparable to standard Glibenclamide. In biochemical observations, PG-EA-NS-B, as well as PG-EA, showed beneficial effects on various hepatic and renal parameters. The pharmacokinetic parameters showed that nanosuspension enhances the absorption and decreases the metabolism of flavonoid actives. The selected nanosuspension and free flavonoid fraction showed rectification of histological changes. The nanosuspension was most stable in cool conditions. PVA based nanosuspensions can be a viable strategy for oral delivery of natural flavonoids, as it significantly affected the absorption and metabolism of flavonoids upon oral administration.

The highly selective C = C reduction of alpha,beta-enones was realized by CF3SO3H-modifying noble-metal-free TiO2 photocatalysis. Selectivity for C = C over C = O reduction was dramatically reversed from fair (similar to 42% without CF3SO3H-modifying) to excellent (> 99%) upon only 6 mol% CF3SO3H loading without any noble-metal additive. Attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR) and C-13-nuclear magnetic resonance (NMR) demonstrated that CF3SO3H modification results in the alpha,beta-enone polar C = O bond sitting away from rather than near to the active sites of polar TiO2 catalysts.
