Abstract Rabbit meat is a good source of protein as compared to beef and chicken. The processing of rabbit meat gives attractive texture with a strong flavor. Charcoal grilling is a well-known cooking method which results in the formation of polycyclic aromatic hydrocarbons. Therefore, to determine the concentration of PAHs, rabbit meat samples were prepared with and without additives and analyzed for six PAHs (naphthalene, fluorene, phenanthrene, anthracene, fluoranthene, and pyrene) using gas chromatography-mass spectrometry (GC-MS). Naphthalene was dominant in all the samples and the highest naphthalene concentration (2.61 µg/g) was found in the foreleg sample (without additives) due to the presence of higher fat molecules. PAHs concentration was found to be significantly (p ≤ 0.05) lower by the addition of antioxidants. Lowest naphthalene concentration was observed in the back sample of seekh kebab (0.77 µg/g) with 1 h marinating duration. The content of pyrene was only noticed in foreleg (0.01 µg/g) and hind leg (0.03 µg/g) samples from reshmi kebab. The content of fluorene was not observed in all the samples.

ABSTRACT Pyrazole being a heterocyclic motif has secured an eccentric status in the field of medicinal chemistry. Pyrazole and its derivatives have tremendous biological applications like anti-cancer, anti-microbial, antiviral, antifungal, anti-inflammatory, analgesic, insecticidal etc. In this review, some recent developments have been reported for the synthesis of biologically active pyrazole based molecules having biological potential such as anti-SIRT1 and SIRT2, anti-FAAH, anti-NOSs, as liver X receptor partial agonist, CB2 receptor ligand and glucagon receptor antagonists.

The aim of present work was to investigate blends of Eudragit® NE 30D with Aquacoat® ECD using different ratios to eliminate curing effect associated with individual polymers. Propranolol HCl 10% w/w was layered onto sugar cores using 5% w/w HPMC as a binder. Drug-layered-cores were coated either with pure or blends of Aquacoat® ECD: Eudragit® NE 30D in a fluidized bed coater to obtain 20% w/w coating level. Talc 35% w/w was used as anti-tacking agent. The pellets were characterized for in vitro dissolution studies, morphology, water uptake-weight loss, osmolality and adhesion of coating after curing at 60 °C or 60 °C/75% RH for 24 h. The findings revealed that Aquacoat® ECD coated pellets showed curing effect due to further gradual coalescence of polymeric particles which resulted into better film formation upon curing. In contrast, the curing effect of Eudragit® NE 30D coated pellets was caused by decrease in adhesion of coatings after curing which provided entirely different swelling behavior of uncured (localized swelling) and cured (uniform swelling) pellets. The undesired curing effect of individual polymers was eliminated by using their blends in appropriate ratio.

In present study synthesis of 99mTc-triamcinolone acetonide (99mTc-TA) complex and its stability using set of quality control parameters such as ligand concentration, reducing agent concentration, pH, temperature and reaction time was assessed. 99mTc-TA complex was characterized in terms of percent (%) yield, stability in saline and serum using chromatographic procedures. Radiochemically the 99mTc-TA complex was found quite stable in saline and serum. After 30 min of reaction the complex showed maximum radiochemical yield of 96.32% which decreased to 96.25 % after 4 h incubation period. In serum, the % yield of radiochemical was remained same up to 2 h which decreased to 93.5% at 24 h time point. Normal biodistribution pattern in Sprague-Dawley rats revealed liver, stomach and kidneys as areas of high 99mTc-TA complex uptake (8.44 ± 1.32, 8.75 ± 1.03 and 12.67 ± 1.21%, respectively) at 1 h post injection time point. Scintigraphy of 99mTc-TA in rabbits showed similar eco as observed in biodistribution study. Based on the promising results obtained in context of in vitro and in vivo stability and biodistribution, 99mTc-TA complex could be further studied to identify the inflammation based diseases.

Alternaric acid is characterized as 1,4-diene, possessing (E)-1,2-disubstituted alkene known for nanomolar phytotoxic and antifungal activities. This article highlights the major synthetic approaches attempted towards the total synthesis of alternaric acid reported by three groups (Ichihara & coworkers, Trost & coworkers and Johnson and Slade) which involved novel pathways for the rapid construction of this functionalized natural molecule.
