Impediment of Cancer by Dietary Plant-derived Alkaloids Through Oxidative Stress: Implications of PI3K/AKT Pathway in Apoptosis, Autophagy, and Ferroptosis.

The adverse toxicities and stemness are two major factors that constrained the usage of therapeutic strategies to target several cancer types. Previous studies explored the efficacy of PI3K/mTOR inhibitors, pan-PI3K inhibitors, and isoform-specific inhibitors against several cancer types, and many of them are currently in clinical trials. The current review described the efficacy of alkaloids derived from dietary plant sources in developing a new anti-cancer to reduce the prevalence of cancer through the modulation of apoptosis, autophagy, and ferroptosis.

Convenient framework of poly functionalized (E)-2-benzylideno-(Z)-carbazolylideno cyanoacetamides via rearrangements as an efficient antibiofilm inhibitors with SAR study.

A simple and one-pot approach for the synthesis of highly functionalized novel (E)-2-benzylideno-(Z)-carbazolylideno cyanoacetamide derivatives from different 2-(2',3',4',9'-tetrahydro-carbazol-1'-ylidene)-propanedinitriles and aryl/heteroaryl carbaldehydes via vinylogous aldol reaction. The structures of the molecules were designated by FT-IR, H NMR, C NMR studies, elemental and X-ray crystallographic analysis. The synthesized pure products have been screened for in vitro antibiofilm inhibitory activity towards antibiotic-resistant pathogenic organisms.

Design and synthesis of novel pyrrolo[2,3-a]carbazoles: 7-Chloro-2-oxo-3a-(2'-oxo-2',3'-dihydro-1'H-indol-3'-yl)-2,3,3a,4,5,10-hexahydro-pyrrolo[3,2-a]carbazole-1-carbonitrile as an efficient anticancer agent.

Highly efficient poly functionalized pyrrolo[3,2-a]carbazoles via ring contraction through rearrangement and intramolecular Michael addition reaction using one pot multicomponent reaction (MCR) is reported for the first time. Free radical scavenging and anticancer activities were determined by DPPH and MTT assays respectively. Of these, compound 8d exhibited most potent activity against HCT-15 human colon cancer cell lines with an IC value of 9.
