Floxuridine (FUDR) is an antimetabolite, floxuridine inhibits thymidylate synthase, resulting in disruption of DNA synthesis and cytotoxicity.

NDNA4 (compound 17) is a selective Hsp90α inhibitor (IC50: 0.34 μM) with permanent charge and low membrane permeability. It demonstrates minimal cytotoxicity against Ovcar-8 and MCF-10A cell lines (IC50 >100 μM) and maintains hERG channel maturation without triggering a heat shock response or degrading Hsp90α-dependent client proteins [1].

Compound 6h (Anticancer Agent 139) exhibits potent anticancer activity, engaging in a π-cationic interaction with Lys352 of Tubulin and demonstrating high efficacy against SNB-19, OVCAR-8, and NCI-H460 with PGIs of 86.61, 85.26, and 75.99, respectively. Moreover, it shows moderate activity against a range of other cancer cell lines — HOP-62, SNB-75, ACHN, NCI/ADR-RES, 786-O, A549/ATCC, HCT-116, and MDA-MB-231 — with PGIs between 51.88 and 67.55 [1].

Thymohydroquinone (Thymoquinol) is a monoterpenoid phenolic compound found in thyme, oregano, and other plants in the labiaceae family. Thymohydroquinone inhibits cancer cell growth, reduces oxidative stress and modulates inflammatory responses, scoured 2, 2-diphenyl-1-PicrylHydrazyl radicals in a cell-free assay (IC50 = 2.4 μg ml), In the oxygen radical absorption capacity (ORAC) test at concentrations of 1.6 to 6.4 μg ml, Its Trolox value was 2.6. Thymus hydroquinone inhibited the growth of A2780, OVCAR-8 and CIS-A2780 ovarian cancer cells (IC50 were 3.1, 8.9 and 9.8 μM, respectively) and human ovarian immortalized epithelial cells (IC50 = 14 μM). It also inhibited Plasmodium falciparum in vitro (IC50 = 15.9 μM).

Isobavachalcone (Corylifolinin) is a chalcone constituent of Angelica keiskei, has potent anti-inflammatory activity, possible can ameliorate neuronal injury in brain diseases associated with inflammation.

NDNA3 (compound 14) selectively inhibits Hsp90α with an IC50 of 0.51 μM, demonstrating low membrane permeability and minimal toxicity to Ovcar-8 and MCF-10A cells, with IC50 values of 12.66 μM and 11.72 μM respectively. It stabilizes hERG channel maturation without eliciting a heat shock response or degrading Hsp90α-dependent client proteins [1].
