A therapeutically active composition of thioretinaco ozonide is provided for providing anticarcinogenic, antineoplastic, antiviral, antiatherogenic, and antiaging benefits having the formula:
(NHTR)
2
CblO
3
O
2
ATP
wherein:
NHTR is N-homocysteine thiolactonyl retinamide;
Cbl is cobalamin;
O
3
is ozone;
O
2 is
oxygen; and
ATP is adenosine triphosphate.
The N-homocysteine thiolactonyl retinamido cobalamin ozonide oxygen adenosine triphosphate complex is further enhanced by utilizing an ozone-resistant liposomal carrier for protecting the composition against oxidative degradation. The ozone-resistant liposomal carrier is advantageously employed to protect a variety of pharmaceutical compositions from oxidative degradation. The ozone-resistant liposomal carrier can also be sterically stabilized to increase the concentration and efficiency of the delivery of pharmaceutical compositions.
提供了一种具有治疗活性的硫代吡啶aco 臭氧烷组合物,该组合物具有抗癌、抗肿瘤、抗病毒、抗动脉粥样硬化和抗衰老的功效,其配方如下:
(NHTR)
2
CblO
3
O
2
ATP
其中
NHTR 是 N-高半胱氨酸硫代内酰基视黄酰胺;
Cbl 是钴胺素;
O
3
是臭氧;
O
2 是
氧气;以及
ATP 是三磷酸腺苷。
通过使用抗臭氧脂质体载体来保护组合物免受氧化降解,N-高半胱氨酸硫醇内酰基视黄醛钴胺臭氧氧三聚腺苷三磷酸复合物的作用进一步增强。抗臭氧脂质体载体可有效保护各种药物组合物免受氧化降解。抗臭氧脂质体载体还可以进行立体稳定化处理,以提高药物组合物的浓度和输送效率。
