Summary: A series of oxazinyl flavonoids were synthesized based on flavone and their activities against tobacco mosaic virus (TMV) and plant pathogenic fungi were investigated. The compounds exhibited moderate to excellent antiviral activities against TMV, with some even surpassing commercially available antiviral agents. They also displayed broad-spectrum fungicidal activities against six kinds of plant pathogenic fungi.

Summary: The main component of orange peel essential oil, limonene, has antibacterial, antiseptic, and antitumor activity, and is of great value in agriculture. It has been found that limonene exhibits excellent antiviral activity against tobacco mosaic virus (TMV), and it triggers a hypersensitive response in tobacco. Limonene also enhances defense enzyme activity and the expression of defense-related genes, as well as the accumulation of salicylic acid. Furthermore, it has been shown to induce plant resistance against various pathogens in pot experiments.

Summary: A pharmacophore fusion strategy was used to design and synthesize new indole-azole hybrids based on the structure of gramine, aiming to enhance its anti-gastric cancer activity. Terminal alkyne group was found to play a crucial role in improving the inhibitory effect, with compound 16h showing the best antiproliferative activity against MGC803 cells. Additionally, compound 16h induced mitochondria-mediated apoptosis, caused cell cycle arrest at G2/M phase, and inhibited the metastasis ability of MGC803 cells.

Summary: Since the isolation of the first natural carbazole alkaloid, murrayanine, from Mwraya Spreng, carbazole alkaloid derivatives have attracted wide attention for their anti-tumor, anti-viral, and anti-bacterial activities. Recent research has shown that carbazole alkaloids and their derivatives exhibit diverse biological activities. This study provides the first comprehensive description of the antifungal and antibacterial activities of carbazole alkaloids in the past decade (2012-2022), including both natural and partially synthesized compounds. The challenges and problems faced by this class of alkaloids are also summarized. This paper will facilitate further exploration of carbazole alkaloids.
