Modification of mesoporous silica SBA-15 with different organic molecules to gain chemical sensors: a review

The recognition of the biologically and environmentally important ions is of great interest in the field of chemical sensors in recent years. The fluorescent sensors as a powerful optical analytical technique for the detection of low level of various analytes such as anions and metal cations have been progressively developed due to the simplicity, cost effective, and selectivity for monitoring ...

UFMylation: A Unique & Fashionable Modification for Life

Ubiquitin-fold modifier 1 (UFM1) is one of the newly-identified ubiquitin-like proteins. Similar to ubiquitin, UFM1 is conjugated to its target proteins by a three-step enzymatic reaction. The UFM1-activating enzyme, ubiquitin-like modifier-activating enzyme 5 (UBA5), serves as the E1 to activate UFM1; UFM1-conjugating enzyme 1 (UFC1) acts as the E2 to transfer the activated UFM1 to the active ...

Chemical modification of fortimicin A.

Chlorination of antibiotic fortimicin A with triphenylphosphine and carbon tetrachloride has been attempted, and 2-chloro-, 2,5-dichloro-, and 2-chloro-4-ene derivatives have been obtained. Successive dehalogenation of the chlorinated fortimicins A with tributylstannane gave the corresponding deoxyfortimicins A. Among five deoxyfortimicins A, 2-deoxyfortimicin A exhibits improved antimicrobial ...
