-
, (2017/04/22)
The invention belongs to the fields of innovative medicines and cosmetics and particularly relates to a preparing method and uses of mangostin shown as a formula (I) and mangostin analogues shown as a formula (II). Alpha-mangostin, beta-mangostin, gamma-mangostin and analogues thereof are respectively prepared through olefination and through controlling conditions for deprotection. According to the method, products are high in purity, operation is simple and convenient, yields are high, costs are low and the method is suitable for large-scale production. On one hand, the beta-mangostin, the gamma-mangostin, beta-methoxy-mangostin, and analogues thereof have ultraviolet absorption ability and ultraviolet light radiation preventing functions so that the beta-mangostin, the gamma-mangostin, the beta-methoxy-mangostin, and the analogues thereof can be adopted as a sun-screening agent separately or compounded with other sun-screening agents and applied into cosmetics; and on the other hand, the beta-mangostin, the gamma-mangostin, the beta-methoxy-mangostin, and the analogues thereof have activity of inhibiting acid sphingomyelinase so that the beta-mangostin, the gamma-mangostin, the beta-methoxy-mangostin, and the analogues thereof can be adopted as acid sphingomyelinase inhibitors and applied for preparation of medicines for preventing and treating acid sphingomyelinase related diseases mainly including cardio cerebrovascular diseases, neurological diseases, liver diseases, lung diseases, autoimmune diseases, infectious diseases and the like.
High-purity α-mangostin process for the synthesis of
-
Paragraph 0064-0066; 0070, (2018/01/19)
The invention relates to a synthesis process method of high-purity natural product alpha-mangostin, comprising the following steps: (1) reacting alpha-mangostin extracted through a process as an initial raw material with different acylation reagents in an alkaline solvent, recrystallizing to remove partial impurity to obtain phenolic hydroxy substituted alpha-mangostin with higher purity; (2) reacting the synthesized intermediate phenolic hydroxy substituted alpha-mangostin with different reagents in the solvent to remove protecting group, reverse extracting through acid-base, recrystallizing, decoloring, and further purifying to obtain the high-purity alpha-mangostin. The method provided by the invention is convenient to synthesize, high in yield, and capable of meeting the demand of the medicine to the quality.
Mangostin the whole synthetic method

, (2016/12/01)
The invention belongs to the field of chemical synthesis and particularly relates to a novel synthesis method of mangostin as shown in the formula (I), wherein the mangostin as a natural effective component has favorable anti-tumor activity, cardiovascular activity, antioxidant activity, anti-inflammatory activity, antibacterial activity and other pharmacological activities. The novel synthesis method comprises the steps: with 1, 7-dihydroxyl-3, 6-dialkoxyl-9H-xanthenone as a raw material, sequentially carrying out nucleophilic substitution, Claisen rearrangement, alkylation, deprotection and the like to obtain alpha-mangostin, beta-mangostin, belt-mangostin-OMe and gamma-mangostin. The novel synthesis method is simple in step and suitable for industrial production.

A total synthesis of α-mangostin 1a has been achieved. The key cyclization reaction to construct the xanthone framework was undertaken by employing the PPh3-CCl4 conditions. The inhibitory activities of 1a and the benzophenone intermediate 16 against the acidic sphingomyelinase were discussed.
