Phenanthridine–pyrene conjugates as fluorescent probes for DNA/RNA and an inactive mutant of dipeptidyl peptidase enzyme [PDF]

open access: goldBeilstein Journal of Organic Chemistry, 2023
Two novel conjugate molecules were designed: pyrene and phenanthridine-amino acid units with a different linker length between the aromatic fragments. Molecular modelling combined with spectrophotometric experiments revealed that in neutral and acidic ...

Synthesis, Bacteriostatic and Anticancer Activity of Novel Phenanthridines Structurally Similar to Benzo[c]phenanthridine Alkaloids [PDF]

open access: yesMolecules, 2018
In this study, we report the synthesis, antibacterial and anticancer evaluation of 38 novel phenanthridines that were designed as analogs of the benzo[c]phenanthridine alkaloids. The prepared phenanthridines differ from the benzo[c]phenanthridines in the

Synthesis and Anticancer Activity Evaluation of Novel Phenanthridine Derivatives

open access: yesFrontiers in Oncology, 2019
Based on the structure of sanguinarine, fourteen phenanthridine derivatives were designed and synthesized in the current study. The cytotoxic activities of synthesized compounds were evaluated against five human cancer cell lines (MCF-7, PC3, Hela, A549,

Selective C‐7 Functionalization of Phenanthridines by Microwave‐Assisted Claisen Rearrangements of 8‐Allyloxyphenanthridines [PDF]

open access: yesChemistryOpen, 2023
Carbon‐carbon bond formation in the phenanthridine 7‐position was achieved by microwave‐assisted Claisen rearrangement of 8‐allyloxyphenanthridines. The reactions took place with excellent regioselectivity and high chemical yields.

Zephycandidine A and Synthetic Analogues—Synthesis and Evaluation of Biological Activity [PDF]

open access: yesMolecules
A convenient total synthesis of the imidazo[1,2-f]phenanthridine-type Amaryllidaceae alkaloid zephycandidine A (3) was developed, which further allowed us to perform modifications of substituents on benzenoid ring A and imidazole ring D.

Structurally Simple Phenanthridine Analogues Based on Nitidine and Their Antitumor Activities

open access: yesMolecules, 2019
A series of novel structurally simple analogues based on nitidine was designed and synthesized in search of potent anticancer agents. The antitumor activity against human cancer cell lines (HepG2, A549, NCI-H460, and CNE1) was performed by 3-(4,5 ...
