Presented herein inter alia are novel compounds and methods of using the same for the treatment of cancers.

The present disclosure relates to novel NMNAT2 activators, semicarbazones and thiosemicarbazones, to processes for preparing them, to pharmaceutical preparations comprising them, to the method by administering the novel semicarbazones and thiosemicarbazones for the treatment and/or prevention of diseases and to the use thereof for the production of a medicament for the treatment and/or prevention of diseases, especially neurodegenerative and age-associated diseases or conditions associated with NAD loss. The present disclosure also provides a method for high throughput screening of NMNAT2 activators.

A sacubitril intermediate, a preparation method therefor, and use thereof. A key intermediate N-Boc amino alcohol represented by formula (10) or formula (10-a) can be efficiently prepared. The intermediate can be used to prepare a neutral endopeptidase (NEP) inhibitor or a prodrug thereof, particularly a NEP inhibitor comprising a skeleton of -amino--biphenyl--methylalkanoic acid or ester, such as sacubitril. Also provided are intermediates for preparing formula (10) or formula (10-a). Raw materials of the process route are cheap, the operation is simple and convenient, the production cost is low, and the method is suitable for industrial production
