The transition metal catalyzed amide bond forming reaction of esters with amines has been developed as an advanced approach for overcoming the shortcomings of traditional methods. The broad scope of substrates in transition metal catalyzed amidations remains a challenge. Here, a manganese(I)-catalyzed method for the direct synthesis of amides from a various number of esters and amines is reported with unprecedented substrate scope using a low catalyst loading. A wide range of aromatic, aliphatic, and heterocyclic esters, even in fatty acid esters, reacted with a diverse range of primary aryl amines, primary alkyl amines, and secondary alkyl amines to form amides. It is noteworthy that this approach provides the first example of the transition metal catalyzed amide bond forming reaction from fatty acid esters and amines. The acid-base mechanism for the manganese(I)-catalyzed direct amidation of esters with amines was elucidated by DFT calculations.

Paragraph 0246; 0249; 0251, (2020/11/27)
Uncoupling of respiration is a well-recognized process that increases respiration and heat production in cells. Provided herein are chemical uncouplers of respiration that are compounds of Formula (I). Also provided are methods for preventing or treating metabolic disorders and modulating metabolic processes using compound of Formula (I).

N-Acyl amino acids directly bind mitochondria and function as endogenous uncouplers of UCP1-independent respiration. We found that administration of N-acyl amino acids to mice improves glucose homeostasis and increases energy expenditure, indicating that this pathway might be useful for treating obesity and associated disorders. We report the full account of the synthesis and mitochondrial uncoupling bioactivity of lipidated N-acyl amino acids and their unnatural analogues. Unsaturated fatty acid chains of medium length and neutral amino acid head groups are required for optimal uncoupling activity on mammalian cells. A class of unnatural N-acyl amino acid analogues, characterized by isoindoline-1-carboxylate head groups (37), were resistant to enzymatic degradation by PM20D1 and maintained uncoupling bioactivity in cells and in mice.

A series of macamides (1-4) and their synthetic analogs (5-14) were synthesized and evaluated for in vitro inhibitory activities against breast cancer cell MCF-7. The results of bioactive assay showed that two of the macamides (compound 1 and 4) and one synthetic analog (compound 5) displayed comparable inhibitory activities against MCF-7 cell line, with IC50 values of 29.6, 36.2 and 27.2 μM, respectively.

A series of fatty acid amides of 3,4-methylenedioxymethamphetamine (MDMA) catechol metabolites were synthesized in order to evaluate their biological activities. Upon administration, all synthesized compounds resulted in negative modulation of food intake in rats. The most active compounds have affinity for the CB1 receptor and/or PPAR-α; part of their biological activity may be caused by these double interactions.
