Indole alkaloids are one of the largest alkaloid classes, proving valuable structural moiety in pharmaceuticals. Although methods for synthesis indole constantly explored, direct single-step these chemical entities with broad diversity remains a formidable challenge. Herein, we report modular assembly tetrahydrocarboline type from simple building blocks single step while showing compatibility medicinally relevant functionality. In this protocol, 2-alkylated or 3-alkylated indoles, formaldehyde, and amine hydrochlorides could undergo one-pot reaction to deliver γ-tetrahydrocarbolines β-tetrahydrocarbolines directly. A wide scope readily available starting materials is applicable process, numerous divergent tetrahydrocarbolines be achieved rapidly. The control deuterium-labelling conducted probe mechanism. And mechanistically, multicomponent relies on multiple alkylamination cascade wherein an unusual C(sp3)-C(sp3) connection was involved process. This method render rapid access pharmaceutically interesting compounds, greatly enlarge library accelerate lead compound optimization thus facilitating drug discovery.

The development of new effective antifungal agents is essential to combat fungal infections. Tetrahydrocarbazole has been exploited as a promising skeleton against various pathogenic microorganisms and used search for novel active compounds. In this study, library composed small tetrahydrocarbazole compounds was screened, potent agent, CAR-8, identified with minimum inhibitory concentration 2-4 μg/mL Candida albicans. CAR-8 showed strong fungicidal activities killed almost all C. albicans within 3 h at 16 μg/mL. At concentrations 2 8 μg/mL, significantly inhibited the formation hyphae biofilms. Moreover, 10 20 mg/kg reduced load improved survival in infection model invertebrate Galleria mellonella. Transcriptome analysis revealed significant changes expression genes associated protein processing endoplasmic reticulum (ER), ER-associated degradation, unfolded response (UPR), which suggested that treatment induced ER stress. resulted phenotypes similar tunicamycin, classical stress inducer. These included nonconventional splicing HAC1 mRNA, fragmented morphology ER, distribution GFP-Snc1 Saccharomyces cerevisiae, cell apoptosis probably caused by More importantly, disruption IRE1 or increased sensitivity confirming UPR signaling pathway critical resistance. Overall, our study identifies stress-induced compound will help discovery drugs.
