Published: July 2019

A novel rearrangement of ester-activated propargylic acetate with isocyanide has been disclosed. This protocol enables a quick synthesis of polysubstituted furan derivatives. The reaction outcome also reveals that the ester group is employed for the construction of a furan ring and an acyl migration is observed.

Acyl-CoA oxidase 1 (ACOX1), a member of the acyl-coenzyme A oxidase family, is considered a crucial regulator whose dysregulation is implicated in the occurrence and progression of various cancers. This study aims to elucidate the impact of ACOX1 in CRC, shedding light on its potential as a therapeutic target. Through analysis of the GEO dataset, it was found that ACOX1 is significantly downregulated in colorectal cancer (CRC), and this lower expression level is associated with a worse prognosis.

Division of Hepatobiliary and Pancreatic Surgery, Department of Surgery, First Affiliated Hospital, School of Medicine, Zhejiang University, Hangzhou, 310003, Zhejiang, China.

Background: Altered metabolism has become an important characteristic of cancer, and acyl-CoA dehydrogenase short-chain (ACADS), a regulator of lipid synthesis, is involved in carcinogenesis-associated metabolic pathways. DNA methylation is an important mechanism for silencing ACADS in various malignancies. However, the specific role of ACADS in hepatocellular carcinoma (HCC) pathogenesis remains poorly understood.

Complementary methods toward the selective functionalization of indole and oxindole frameworks employing an alternative strategy in heteroaryl C-H functionalizations are presented herein. This work focuses on a catalyst-controlled, site selective C-H activation/functionalization of 3-acyl indoles, wherein an amide serves as a robust and versatile directing group capable of undergoing concomitant 1,2-acyl translocation/C-H functionalization in the presence of a Rh/Ag co-catalysts to provide the cross-coupled adducts in high yields. In contrast, the use of Ir/Ag catalysts subverted the 1,2-acyl migration to afford the corresponding C2-functionalized products in good to excellent yields.

Triple-negative breast cancer (TNBC) has profound unmet medical need globally for its devastating clinical outcome associated with rapid metastasis and lack of targeted therapies. Recently, lipid metabolic reprogramming especially fatty acid oxidation (FAO) has emerged as a major driver of breast cancer metastasis. Analyzing the expression of major FAO regulatory genes in breast cancer, we found selective overexpression of acyl-CoA synthetase 4 (ACSL4) in TNBC, which is primarily attributed to the absence of progesterone receptor.
