Cataract is the principal cause of preventable blindness in older people globally. Intraocular surgeries stimulate multiple postoperative inflammatory responses. The current clin. treatment by dropping prednisolone acetate (PA) and levofloxacin (LF) suffers from drawbacks, such as low bioavailability and poor patient compliance. This study aims to develop a rationally designed thermoresponsive formulation combining PA and LF using nancomposites of mesoporous silica nanoparticle (MSN) and thermo-nanogel (thermogel) (PA@MSN-LF@Thermogel). The in vitro release profiles of PA and LF from PA@MSN-LF@Thermogel are tailor-made to adapt to wound healing by a sustained release of 28 days. PA@MSN-LF@Thermogel exhibits little cytotoxicity to human Tenon′s fibroblasts and human corneal epithelial cells, while presents excellent in vitro antibacterial effectiveness to Staphylococcus bacteria. After implanted into the rabbit eye by a subconjunctival injection, PA@MSN-LF@Thermogel displays overwhelming anti-inflammatory and antibacterial effectiveness up to 21 days using only one-eighth of the total dose, compared with PA and LF eye drops. The formulation does not cause any ocular hypertension and noticeable histopathol. abnormality which indicate good biosafety. This thermoresponsive nanocomposite formulation is thus a promising drug delivery alternative for treatment of postoperative inflammation after intraocular surgeries. This study involved multiple reactions and reactants, such as 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0Category: thiazole).
3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0) belongs to thiazole derivatives. The thiazole ring has been identified as a central feature of numerous natural products, perhaps the most famous example of which is epothilone. The pyridine-type nitrogen in the thiazole ring deactivates the ring for electrophilic substitution reactions, which is further reduced in acid due to protonation of the thiazole ring.Category: thiazole
