Opis:
Due to the need for molnupiravir (EIDD-2801, MK-4482) anti-COVID-19 agent, in the present report, we have systematically investigated the effect of different solvents, acids (as catalyst), temperature, and other parameters which play rolls in De-ketalization process of its key intermediate. At the first glance, it might seem to be easy, but the complex nature of MK-4482 agent, and also the ultra-high purity of the crude (which is required for an active pharmaceutical ingredient (API)), make this process more complicated. As would be shown below, even a little change in the type of solvent, solvent ratio, the type or the amount of catalyst, and the temperature could directly change the reaction fate (it may lead to emergence of un-controlled impurity profile, or even it could block the reaction). However, in this work, we have been able to run this de-ketalization process only in water as the whole of the system. Here, it was observed that the high energy water molecules have been able to hydrolyze the ketal intermediate of MK-4482.

Opis:
Efforts were made to demonstrate that in biorefineries it is possible to manufacture all the commodities required for maintaining human civilisation on the current level. Biorefineries are based on processing biomass resulting from photosynthesis. From sugars, oils and proteins, a variety of food, feed, nutrients, pharmaceuticals, polymers, chemicals and fuels can further be produced. Production in biorefineries must be based on a few rules to fulfil sustainable development: all raw materials are derived from biomass, all products are biodegradable and production methods are in accordance with the principles of Green Chemistry and Clean Technology. The paper presents a summary of state-of-the-art concerning biorefineries, production methods and product range of leading companies in the world that are already implemented. Potential risks caused by the development of biorefineries, such as: insecurities of food and feed production, uncontrolled changes in global production profiles, monocultures, eutrophication, etc., were also highlighted in this paper. It was stressed that the sustainable development is not only an alternative point of view but is our condition to survive.
