Coriander: A holistic outlook on its chemistry and pharmacology.

Coriander (Coriandrum sativum L.) is a nutraceutically renowned annual herb from Apiaceae family and used in cuisines in different countries in different ways to enhance the tastes, flavour and nutritional values of foods. Fruit (seed) has several medicinally valuable chemical components viz.

Garlic against Heart-related Ailments: Chemistry, Pharmacology, and Future Perspective.

Background: Allium sativum L. (Garlic) is a well-recognized plant of great nutraceutical value with pharmacological evidences. It is full of dietary as well as pharmaceutical properties and has been used in traditional medications for a long time.

Fungal assisted bio-treatment of environmental pollutants with comprehensive emphasis on noxious heavy metals: Recent updates.

In the present time of speedy developments and industrialization, heavy metals are being uncovered in aquatic environment and soil via refining, electroplating, processing, mining, metallurgical activities, dyeing and other several metallic and metal based industrial and synthetic activities. Heavy metals like lead (Pb), mercury (Hg), cadmium (Cd), arsenic (As), Zinc (Zn), Cobalt (Co), Iron (Fe), and many other are considered as seriously noxious and toxic for the aquatic environment, human, and other aquatic lives and have damaging influences. Such heavy metals, which are very tough to be degraded, can be managed by reducing their potential through various processes like removal, precipitation, oxidation-reduction, bio-sorption, recovery, bioaccumulation, bio-mineralization etc.

Correlating multi-functional role of cold shock domain proteins with intrinsically disordered regions.

Cold shock proteins (CSPs) are an ancient and conserved family of proteins. They are renowned for their role in response to low-temperature stress in bacteria and nucleic acid binding activities. In prokaryotes, cold and non-cold inducible CSPs are involved in various cellular and metabolic processes such as growth and development, osmotic oxidation, starvation, stress tolerance, and host cell invasion.

Nano-reduction of gold and silver ions: A perspective on the fate of microbial laccases as potential biocatalysts in the synthesis of metals (gold and silver) nano-particles.

Nanoparticles of metals have momentous place in the field of biological as well as pharmaceutical chemistry due to which in the present scenario of the research, this field is of auspicious interest. Synthesis of metal nanoparticles via microbial assistance is a burning field for their green synthesis. In this direction, microbial enzymes play significant role, out of which microbial laccases may also be a talented biocatalyst for the synthesis of metal nanoparticles considering its efficacy and interesting promising biological applications.

Purification, characterization and synthetic application of a thermally stable laccase from Hexagonia tenuis MTCC-1119.

A thermally stable laccase was purified from the culture filtrate of Hexagonia tenuis MTCC-1119. The method involved concentration of the culture filtrate by ammonium sulphate precipitation and an anion-exchange chromatography on diethylaminoethyl (DEAE) cellulose. The sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) and native polyacrylamide gel electrophoresis (native-PAGE) both gave single protein bands, indicating that the enzyme preparation was pure.

Selective oxidation and N-coupling by purified laccase of xylaria polymorpha MTCC-1100.

The chemical route of oxidation of methyl group to its aldehyde is inconvenient because once a methyl group is attacked, it is likely to be oxidized to the carboxylic acid and it is very difficult to stop the reaction at the aldehyde stage. Fungal laccases can be used for such oxidation reaction and the reaction can be completed sharply within 1-2 hrs. Coupling of amines are another important reactions known forfungal laccases; coupling reactions generally take 3-7 hrs.

Role of laccase from Coriolus versicolor MTCC-138 in selective oxidation of aromatic methyl group.

Now a day, laccases are the most promising enzymes in the area of biotechnology and synthesis. One of the best applications of laccases is the selective oxidation of aromatic methyl group to aldehyde group. Such transformations are valuable because it is difficult to stop the reaction at aldehyde stage.
