, p. 188 - 194 (2021/02/03)
Strecker reaction is widely applied for the synthesis of amino acids from aldehydes, amines and cyanides. Herein, we report the FeI2-catalyzed reductive Strecker type reaction of formamides instead of aldehydes to produce amino acetonitriles. The challenging capture of carbinolamine intermediates by CN? was achieved via Fe catalysis. This approach afforded better yields than the use of Ir- or Rh-catalysts. The application ability of this methodology is demonstrated by 1) one-pot construction of (13C labeled) complex molecules from CO2 via amino acetonitrile intermediates and 2) convenient production of homologated carboxylic acids from aldehydes.

Paragraph 0014; 0021-0022, (2021/06/21)
The invention belongs to the field of biological medicine, and particularly relates to application and a preparation method of an oxadiazole hydroxamic acid anti-tumor metastasis compound. Histone deacetylase (HDAC) and histone acetyltransferase (HAT) have a synergistic effect to jointly regulate and control the acetylation level of histone lysine residues. It is proved that HDACi (histone deacetylase inhibitors) function in the tumor development process through a variety of mechanisms. The oxadiazole hydroxamic acid derivatives have a variety of pharmacological properties, such as anti-tumor, anti-inflammatory and antibacterial activity. According to the invention, an oxadiazole structure is taken as a CAP region and is combined with a hydroxamic acid structure, a novel anti-tumor metastasis histone deacetylase inhibitor is synthesized, and the synthesized compound is subjected to an inhibition experiment on HDAC1 enzyme activity.

Histone deacetylases (HDACs) has proved to be promising target for the development of antitumor drugs. In this study, we reported the design and synthesis of a class of novel hydroxamate-based bis-substituted aromatic amide HDAC inhibitors with 1,2,4-oxadiazole core. Most newly synthesized compounds displayed excellent HDAC1 inhibitory effects and significant anti-proliferative activities. Among them, compounds 11a and 11c increased acetylation of histone H3 and H4 in dose-dependent manner. Furthermore, 11a and 11c remarkably induced apoptosis in HepG2 cancer cells. Finally, the high potency of compound 11a was rationalized by molecular docking studies.

Using cyanoacetic acid as a masked electrophile, a new cyanomethylation reaction of amines and carboxylic acids was developed, producing a variety of α-aminonitriles and cyanomethyl esters with good yields and excellent functionality tolerance. This protocol features simple manipulation, inexpensive reagents, and a wide substrate scope. Iodoacetonitrile was generated in situ from the iodination-decarboxylation of cyanoacetic acid in this transformation.

A series of tetrazole derivatives were synthesized and characterized by NMR, IR, MS and HRMS spectroscopy. The bioactive assay manifested that most of the target compounds exhibited good antifungal activity, especially compound 6g displayed comparable or even stronger antifungal efficiency in comparison with the reference drug Fluconazole. The combination of tetrazole derivative 6g with antibacterials Chloromycin and Norfloxacin, or antifungal Fluconazole respectively was more sensitive to methicillin-resistant MRSA and Fluconazole-insensitive Aspergillus flavus. Further research revealed that compound 6g could effectively intercalate into Calf Thymus DNA to form a 6g-DNA complex which might block DNA replication to exert its good antimicrobial activities.
