contg. an anilidovinyl- or phenylimino-ethylidene gp., effected in the presence of an aliphatic acid anhydride and of a tert. aliphatic amine. Reaction is fast, allowing prepn. in the cold, and dyes are obtd. in high yield.GLOCKNER, HANS, DR., PULLACH...
and the imidazolyl ring of histidines. However, acylation of cysteine, tyrosine, andhistidineside chains forms unstable complexes that are easily reversible to regenerate the original group. Only amine functional groups of proteins are stable to acylation with anhydride reagents, formingamidebonds (Fraen...

These materials were prepared with modified hyaluronic acid-methacrylic anhydride (HA-MA) and hyaluronic acid-3,3-dithiobis (propionylhydrazide) (HA-SH) and crosslinked with ultraviolet light. The authors concluded that the HA-MA hydrogel showed higher swelling ratio and faster degradation rate. ...
Succinic anhydride is the dehydration product of the acid. Succinic acid was first obtained as the distillate from amber (Latin, Succinum) for which it is named. It occurs in beet, brocoli, rhubarb, sauerkraut, cheese, meat, molasses, eggs, peat, coal, fruits, honey, and urine (Gardner,...
An important feature of this reaction is that no part of the carbodiimide is incorporated into the transient species; that is, the fuel is decoupled from the structure-and thus function-of the assembled state. We show that intramolecular anhydride formation of oligo(ethylene glycol) diacids gives...
Since quinoline-based MC16266awas firstly reported as Gcn5 HAT inhibitors in 2005, other derivatives were investigated on different HAT families including GNAT and p300/CBP families [157–161]. Employingo-nitrobenzaldehyde or isatoic anhydride with ethylβ-oxo ester as the starting materials,6aand6c...
subtd. polyimide, polyamide and polyimide-amide resins are prepd. by reacting a polyisocyanate with alkali(ne earth) metal salts and/or esters of aromatic acids with 3 or 4 COOH gps. or of aliphatic or aromatic dicarboxylic acids with non-adjacent COOH gps., but pref. with salts of Na, ...
