A series of esters with the general formula C6H13COOR, where R = Me, Et, n-Pr, i-Pr, n-Bu, i-Bu, s-Bu and t-Bu, was used as substrates. At high conversions, manganese cata...

The microbial transformations of testosterone and testosterone heptanoate by four fungi: Absidia griseolla var. igachii PTCC 5260, Acremonium chrysogenu PTCC 5271, Fusarium fujikuroi PTCC 5144, and Fusarium solani complex PTCC 5285 were investigated for the first time. Incubation of testosterone...

An in-situ forming implant formulation of naltrexone (NTX) was achieved based on a minimum initial burst release of NTX in the in-vitro release medium using a Box-Behnken design. Variables such as percent of copolymer by weight, copolymer composition (PLGA 756s: PLGA 504H), and percent ethyl hep...

Liquid–liquid equilibrium (LLE) data for the ternary systems of (water + formic acid + ethyl heptanoate) and (water + acetic acid + ethyl heptanoate) were investigated at 288.15, 298.15, and 308.15 K and atmospheric pressure. The tie-line data was determined experimentally for each temperature....

Fatty acid ethyl esters are the main components of biodiesels, the increasing use of biodiesels requires the study of thermophysical properties. This paper measured the speed of sound and the thermal diffusivity in liquid ethyl heptanoate from 293.15 K to 483.15 K and up to 10 MPa using light sc...

A direct and selective method for the α,β-dehydrogenation of esters using palladium catalysis in the presence of free OH and NH functionalities is reported herein. Allyl-palladium catalysis allows for preservation of readily oxidizable functionalities such as amines and alcohols. Furthermore, ...

The present work illustrates the incorporation of ultrasound and its improved impact in the lipase catalysed esterification. Synthesis of isoamyl butyrate from isoamyl alcohol and butyric acid using immobilised Novozym 435, has been carried out in the presence of ultrasound. The optimisation of ...

The enzymatic synthesis of isoamyl butyrate possessing fruity banana flavour and under high demand in commercial market, is carried out under microwave irradiation. The influence of various reaction parameters was studied and optimised that drive the reaction under solvent free condition to achi...

Iridoid compounds have been reported to be accumulated in the dried fruits of Gardenia jasminoides (Rubiaceae), which are used in traditional Chinese medicine. These compounds exhibit obvious pharmacological activities, including effective protective effects on the liver and therapeutic efficacy...

The present study aims to explore the performance, emission and combustion characteristics of CI engine fuelled with gutter oil/waste cooking oil obtained from vegetarian and non-vegetarian restaurant used for frying french fries (WCO1) and chicken (WCO2) respectively. The engine used for testin...

The role of Geraniol was studied on the transgenic Drosophila model flies expressing normal human alpha synuclein (h-αS) in the neurons. Geraniol at final concentration of 10, 20 and 40 μM were mixed in the diet and the flies were allowed to feed on it for 24 days. The effect of geraniol was s...

The present study was planned to assess the possible protective effect of geraniol on cardiovascular complications in an animal model with diabetes. Diabetes was induced in rats by a single streptozotocin injection. In the treated group, geraniol (150 mg kg−1 day−1) was administered orally start...

In humans, the occurrence of bacterial communities in the form of biofilm is considered as a major intrinsic factor accountable for a variety of stubborn infections. Staphylococcus aureus and S. epidermidis have gained considerable attention in clinical settings owing to the formation of intract...

AimsCisplatin (CP) is a widely used broad-spectrum antineoplastic agent used to treat a variety of human malignancies. Neurotoxicity is clinically evident in patients who have undergone a full course of chemotherapy. The aim of this study was to investigate the possible protective effects of thy...

Manipulation of monoterpene synthases to maximize flux towards targeted products from GPP (geranyl diphosphate) is the main challenge for heterologous monoterpene overproduction, in addition to cell toxicity from compounds themselves. In our study, by manipulation of the key enzymes geraniol syn...

Geraniol is an important monoterpene alcohol with various industrial applications. The biological synthesis of geraniol requires the activity of geraniol synthase (GES). Despite several engineering efforts to improve catalytic rates of GES, overall efforts have been limited by the lack of a high...

Geraniol is a common component of essential oils of various plant species and is widely used in cosmetics, perfumery and household products. In the present study, we investigated the cytotoxic, genotoxic and antioxidant activities of different concentrations of the monoterpenoid geraniol and its...

Geraniol, an active constituent of rose and palmarosa essential oils, possesses several pharmacological properties, including antioxidant, antibacterial and antiulcer activity.
