The values of charge and electrophoretic mobility of a protein are changed upon acylation of its α- and Lys ε-NH3+ groups. Partial acylation of the amino groups of a protein results in a set of derivatives that is often resolved by c
Preparation of N-hydroxysuccinimido esters via palladium-catalyzed carbonylation of aryl triflates and halides

N-Hydroxysuccinimido esters of aromatic carboxylic acids (a.k.a. active esters) can be made using a potentially general, one-step procedure via Pd-catalyzed carbonylation of an aryl triflate or aryl iodide with CO and N-hydroxysuccinimide. Excellent yields (up to 94%) were observed when the reaction was done in DMSO at 70°C and 1 atmosphere of CO pressure.
Eight-membered ring-containing jadomycins: Implications for non-enzymatic natural products biosynthesis

Jadomycin Oct (1) was isolated from Streptomyces venezuelae ISP5230 and characterized as a structurally unique eight-membered l-ornithine ring-containing jadomycin. The structure was elucidated through the semisynthetic derivatization of starting material via chemoselective acylation of the l-ornithine α-amino group using activated succinimidyl esters. Incorporation of 5-aminovaleric acid led to jadomycin AVA, a second eight-membered ring-containing jadomycin. These natural products illustrate the structural diversity permissible from a non-enzymatic step within a biosynthetic pathway and exemplifies the potential for discovery of novel scaffolds.
N -Heterocyclic carbene (NHC) catalyzed amidation of aldehydes with amines via the tandem N -hydroxysuccinimide ester formation

A facile method for the amidation of aldehydes by a cascade approach was developed. This methodology, reported for the first time, uses a N-heterocyclic carbene (NHC) as the catalyst, and N-hydroxysuccinimide (NHS) mediated synthesis of amides utilising TBHP as the oxidant. Various substituted aldehydes reacted smoothly with NHS giving the corresponding active esters in moderate to good yields, which facilely converted into amides in one pot. In addition, the drug moclobemide was synthesized to represent the practical utility of the developed methodology. This journal is
CHEMOSELECTIVE SENSITIVITY BOOSTER FOR TAGGING A PEPTIDE, PEPTIDE CONJUGATE, OR SIMILAR REACTIVE MOLECULE

Page/Page column 39, (2020/12/29)
The invention pertains to chemoselective sensitivity booster for tagging a peptide, peptide conjugate, or similar reactive molecule for analysis of a peptide, protein, antibody, protein bioconjugate, antibody bioconjugate, and similar analytes. The sensitivity booster comprises of sp2 or sp3 nitrogen centers in combination with hydrophobic carbon chains linked with an electrophile or nucleophile for attachment with a peptide, peptide conjugate, or molecules with similar reactivity.
