  Synthesis and characterization of new and potent α-lipoic acid derivatives

  摘要：

  alpha-Lipoic acid [5-[1,2]-dithiolan-3-yl-pentanoic acid (LA)] is a natural antioxidant and cofactor of several enzymes. It increases the glucose transport activity in skeletal muscles and adipocytes in a non-insulin dependent manner. Therefore, LA is widely used in Type 2 diabetic patients as an oral auxiliary drug. However, large doses of LA (0.8-1.8 gr/day po) are required due to its unfavorable pharmacokinetic parameters. In order to improve these parameters, we synthesized ester and amide LA derivates. Two of these newly synthesized compounds, 5-[1,2]-dithiolan-3-yl-pentanoic acid 3-(5-[1,2]dithiolan-3yl-pentanoylamino)-propyl]-amide (AN-7) and 5-[1,2]-dithiolan-3-yl-pentanoic acid 3-(5-[1,2]-dithiolan-3yl-pentanoyloxy)-propyl ester (AN-8) augmented the rate glucose transport in myotubes in culture in the absence or presence of insulin. Their potency was 12-fold higher than that of the parent compound; their maximal stimulatory effect was 1.5-fold higher than that of LA. When tested in vivo in streptozotocin-diabetic C57/Black mice, AN-7 (10 mg/kg/day for 2 weeks, sc) reduced blood glucose level by 39% while a higher dose of LA (50 mg/kg/day for 2 weeks, sc) lowered it by 30%. These results indicate that AN-7 is more potent than LA in augmenting glucose transport in skeletal muscles and reducing blood glucose in diabetic animals. (C) 2003 Elsevier Ltd.

  Five lipoic acid esters were synthesized, and their nanoforms based on copolymer Pluronic F68 and phosphatidylcholine were obtained. The most pronounced antioxidant effect on neutrophils activated by phorbol-12-myristate-13-acetate was shown by the nanodispersion containing the derivative of lipoic acid with hexane-1,6-diol, reducing the concentration of reactive oxygen species by 7.5 times.

  The present invention is directed to multiple a-lipoic acid-containing hydrophobic compounds (mALAs) capable of acting as scavengers of free radicals, metals and reactive oxygen species (ROS). Methods of synthesizing novel antioxidant mALAs, spontaneous emulsification or nanoprecipitaion thereof to produce antioxidant nanospheres and their use in preventing or treating diseases or conditions caused by oxidative stress and other free radical mediated conditions are also described. Another aspect of this invention is the use of these antioxidant nanospheres for the preparation of antioxidant particulate delivery system of therapeutic agents.
