摘要:The present invention provides for a method to deconstruct a biomass comprising: (a) introducing one or more individual components of an ionic liquid (IL) or deep eutectic solvent (DES) to a biomass, wherein the one or more individual components, and optionally any components already present in the biomass, form an IL or DES, or mixture thereof, which solubilizes the biomass to form a solubilized biomass mixture, wherein at least one individual component is introduced to the biomass separately from any other individual component; (b) optionally introducing an enzyme and/or a microbe to the solubilized biomass mixture such that the enzyme and/or microbe produces a sugar from the solubilized biomass mixture; and, (c) optionally separating the sugar from the solubilized biomass mixture.

标 题 :Serpentine, alstonine and sempervirine drugs for the specific inhibition of tumurous and cancerous cells
摘要:1. Pharmaceutical compositions having preferential action on the replication of DNA and the synthesis RNA in tumorous, cancerous and viral cells, characterized in that they consist of microgranules having a neutral central core, at least one first intermediary layer comprising at least one alkaloid of the group of beta-carbolines of the type serpentine, alstonine, sempervirine and flavopereirine, and at least an outer layer made up by a microporous envelope, comprising at least a natural and/or synthetic polymer of the type : shellac, arabic gum, gelatine, cellulose, ethyl cellulose, cellulose acetophtalate, cellulose triacetate, polyvinyl pyrrolidone, polyoxyethylene glycol, methacrylates and styrene-acrylonitrile copolymers.
