The present invention relates to nitric oxide donor carnosine derivatives having a great efficacy in reducing elevated intraocular pressure, to processes for their preparation and to their use in the treatment and/or prophylaxis of glaucoma and ocular hypertension.
The prodrugs were designed considering their expected lipophilicity and their hydrolysis predicted by docking simulations on the most important human carboxylesterase (hCES1). The stability and metabolic profile of the prodrugs were studied by incubating them with rat and human serum and liver fractions. The octyl ester of D‐CAR (compound 13) was chosen as a candidate for further pharmacological studies
D-Camosine lipophilic derivatives are disclosed, characterized by higher bioavailability than L-camosine and intended for the pulmonary distribution where they can exert detoxifying activity on the cytotoxic carbonyl compounds induced by cigarette smoke.

Abstract Naturalantioxidants such as carnosine and α-tocopherol (vitaminE) provide protection against several oxidative stress–related diseases such as atherosclerosis and Alzheimer's. The synthetic combination of α-tocopherol and carnosine can take advantage of the cellular transport mechanism of α-tocopherol by α-tocopherol transfer protein (α-TTP) to colocate α-tocopherol and carnosine at the

l-Carnosine (β-alanyl-l-histidine, LCar) is the most widely and abundantly distributed copper(II)-coordinating endogenous dipeptide. Though its physiological role has not been completely understood yet, many functions have been proposed for this compound. LCar might be crucial in the potential reduction or prevention of several pathologies in which the metal ions are thought to be involved. The potential
