Enzymically synthesized poly(glycerol adipate) (PGA) has shown a palette of key desirable properties required for a biomaterial to be considered a ′versatile polymeric tool′ in the field of drug delivery. PGA and its variations can self-assemble into nanoparticles (NPs) and interact at different levels with small active mols. PGA derivatives are usually obtained by functionalising the glyceryl side hydroxyl group present along the main polymer scaffold. However, if the synthetic pathways are not finely tuned, the self-assembling ability of these new polymeric modifications might be hampered by the poor amphiphilic balance. For this reason, we have designed a straightforward one-pot synthetic modification, using a small library of diols in combination with glycerol, aimed at altering the backbone of the polymer without affecting the hydrophilic glyceryl portion. The diols introduce addnl. functionality into the backbone of PGA alongside the secondary hydroxyl group already present. We have investigated how extra functionalities along the polymer backbone alter the final polymer reactivity as well the chem. and biol. properties of the nanoparticles. In addition, with the intent to further improve the green credentials of the enzymic synthesis, a solvent derived from renewable resources, (2-MeTHF) was employed for the synthesis of all the PGA-variants as a replacement for the more traditionally used and fossil-based THF. In vitro assays carried out to evaluate the potential of these novel materials for drug delivery applications demonstrated very low cytotoxicity characteristic against NIH 3T3 model cell line. This study involved multiple reactions and reactants, such as 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0Application of 38215-36-0).
3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0) belongs to thiazole derivatives. Thiazoles are a class of five-membered rings containing nitrogen and sulfur with excellent antitumor, antiviral and antibiotic activities. The nitrogen in thiazole is sp2 hybridized and the lone pair of electrons localized on the nitrogen is less reactive due to increased aromatic character and decreased basicity. It is protonated and alkylated/acylated at nitrogen forming hydrochloride and quaternary thiazolium salt.Application of 38215-36-0
