Upregulation of p53 through induction of MDM2 degradation: Amino acid prodrugs of anthraquinone analogs

Previously, we reported a class of MDM2-MDM4 dimerization inhibitors that upregulate p53 and showed potent anticancer activity in animal models. However, water solubility hinders their further development. Herein we describe our effort to develop a prodru

A biocatalytic approach towards the preparation of natural deoxyanthraquinones and their impact on cellular viability

Herein, a two-step chemoenzymatic process for the synthesis of medicinally important 3-deoxygenated anthra-9,10-quinones is developed. It involves a regio- and stereoselective reduction of hydroanthraquinones to (R)-configured dihydroanthracenones using an anthrol reductase of T. islandicus, followed by oxidation and dehydration to obtain deoxyanthraquinones in 65-80% yield. Comparison of the cell viability of normal human kidney HEK293 cells between anthraquinones and their deoxy derivatives revealed less toxicity for the latter.

Preparation method of parietic acid-amino acid conjugate

The invention belongs to the technical field of organic compound synthesis, and particularly relates to a preparation method of a parietic acid-amino acid conjugate. The preparation method comprises the following steps of weighing 1 to 2g of methyl methacrylate; putting the methyl methacrylate into a reaction container; then adding 35 to 45ml of DMAP, 0.3 to 0.8g of strong base sodium hydride and1 to 3g of halohydrocarbon at the reaction temperature of 100 to 120 DEG C for the reaction time of 10 to 25min; then, adding 40 to 60 ml of hydrochloric acid solution; performing constant temperaturereaction for 5 to 10min; after the reaction is completed, performing extraction by dichloromethane; adding the extracted products into 35 to 38ml of sodium hydroxide solution; performing reaction atthe temperature of 50 to 60 DEG C for 15 to 30min; performing high-speed stirring; then regulating the pH into a weak acid state; adding 1 to 3g of amino-acid ester; performing room temperature stirring reaction for 5 to 10min; adding 40 to 60ml of hydrochloric acid solutions; performing constant temperature reaction for 5 to 10min; after the reaction is completed, performing extraction for 2 to 4times by dichloromethane; after the solid is separated, performing filtering; performing drying by anhydrous sodium sulfate; obtaining a finished product. The preparation method has the advantages that the dissolution is easy; the bioavailability is high; the process equipment requirement conditions are low; the process steps are simple; the synthesis rate is high, and the like.
