Osthole: Synthesis, Structural Modifications, and Biological Properties

Mini-Reviews in Medicinal Chemistry, 2022
Abstract: Osthole, a naturally occurring coumarin-type compound, is isolated from the Chinese herbal medicine Cnidium monnieri (L.) and exhibits a broad range of biological properties. In this review, the total synthesis and structural modifications of osthole and its analogs are described.

Histone modifications dictate specific biological readouts

Journal of Genetics and Genomics, 2009
The basic unit of chromatin is the nucleosomal core particle, containing 147 bp of DNA that wraps twice around an octamer of core histones. The core histones bear a highly dynamic N-terminal amino acid tail around 20-35 residues in length and rich in basic amino acids.

Protein modification and its biological role

International Journal of Biochemistry, 1985
The modifications present on a polypeptide play an important role in determining its eventual fate. Modifications, particularly proteolysis, are important in the generation of biological activity. Modifications are used to "target" particular polypeptides to specific cellular locations.

Chitosan: Structural modification, biological activity and application

International Journal of Biological Macromolecules, 2020
Many by-products that are harmful to the environment and human health are generated during food processing. However, these wastes are often potential resources with high-added value. For example, crustacean waste contains large amounts of chitin. Chitin is one of the most abundant polysaccharides in natural macromolecules, and is a typical component of

Biological modification of oil composition

Journal of the American Oil Chemists' Society, 1985
AbstractProspects for modification of palm oil composition through oil palm breeding, tissue culture and enzyme‐catalyzed transesterification are reviewed. Present emphasis in oil modification is toward greater unsaturation. The greatest prospect for this area lies in the interspecific hybridization ofE. oleifera andE. guineensis.

MODIFICATION OF BIOLOGIC RESPONSE IN EXPERIMENTAL HYPERSENSITIVITY

Journal of the American Medical Association, 1949
Recently there has been wider acceptance of the view that a particular group of diseases and certain reactions to therapeutic agents occur on the basis of an acquired hypersensitivity. There is evidence that rheumatic fever, glomerulonephritis, serum sickness and periarteritis nodosa belong in this category,1and some have added to this group acute ...

Physical and biological modification of carbonic sorbents

Clinical Materials, 1992
Activated carbons are usually considered as non-specific sorbents. However, their specificity and effectiveness may be increased by physical and biological modifications. This paper gives our approach and discusses the results of some related recent studies.

Gas Plasma Surface Modification for Biological Assays

2023
Surface chemistry plays an important role in the adsorption and immobilization of enzymes and antibodies. Gas plasma technology performs surface preparation that assists in the attachment of molecules. Surface chemistry helps to manage a material's wetting, joining, or the reproducibility of surface interactions.
