Method for efficiently synthesizing primary amines
Disclosed is a method for efficiently synthesizing primary amines, which comprises using carbonyl compounds or alcohol compounds as reaction substrate, liquid ammonia or alcohol solutions of ammonia as nitrogen source, and hydrogen as hydrogen source, and reacting in reaction medium catalyzed by a cobalt-based catalyst to obtain the primary amines. Due to high catalytic activity, the method can realize the reductive amination of carbonyl compounds and the hydrogen-borrowing amination of alcohol compounds at low temperatures in a short time to obtain the primary amines with high yield, and is applicable to a wide range of substrates. The obtained primary amines can be used as raw materials with high extra value for producing polymers, medicines, dyes and surfactants. Further, the cobalt-based catalyst has a good industrial application prospect because it is magnetic which can facilitate separation and recycling of the catalyst. Moreover, the inexpensive cobalt-based catalyst can significantly reduce industrialization cost.
Preventive and therapeutic approach for aberrant cell differentiation and ISR-associated diseases
The present invention describes a method of preventing, ameliorating and/or treating disorders or diseases associated with the integrated stress response (ISR) involving the p-eIF2α pathway arising from various cellular stresses such as oxidative stress, hypoxia and ER stress, chronic or prolonged bio-mechanical stress. In one embodiment, the present invention provides a method which prevents or alleviates aberrant cell differentiation that is caused by the activation of the integrated stress response and thereby prevents or alleviates conditions, disorders or diseases resulting therefrom. In one embodiment, ISR-associated diseases subject to the present invention include but are not limited to skeletal disorders including disc degeneration, MCDS and other skeletal dysplasias, cancers, inflammatory diseases, diabetes, fibrosis, obesity and neurodegenerative diseases. In another embodiment, the present invention provides a method of using a p-eIF2α-modulator for the prevention or treatment of conditions, disorders or diseases described herein.
