Reduction of the keto group was found to decrease activity fourfold, corroborating the irreplaceable role of this sites electronic properties as a hydrogen-bonding receptor in mediating target interactions ( 2.3 C-3 hydroxyl group modification 2.3.1 Esterification The incorporation of nitrogen-containing heterocyclic moieties into C-3 hydroxyl group esterification modifications has been shown to substantially augment cytotoxic potency (Figures 1a,b) were found to exhibit the potent activity against four cancer cell lines (MCF-7, HCT-116, HeLa, and HepG2), with IC 50 values below 7 M (Figure 1c) demonstrated potent efficacy, with IC 50 values of 18.68 M, 13.16 M, and 7.48 M against HBsAg secretion, HBeAg (Hepatitis B e Antigen) secretion, and HBV (Hepatitis B Virus) DNA replication, respectively ( In a molecular hybridization approach, the 3-O-(3,4,5-trimethoxycinnamoyl) derivative (Figure 1d) exerted its effect through a unique non-nucleoside mechanism by interfering with the transcriptional regulation of the HBV X promoter and enhancer I, achieving a 16-fold increase in DNA replication inhibitory activity (IC 50 = 2.44 M) compared to the parent compound (Figure 1e), for example, exhibited enhanced anti-hepatitis B virus activity (IC 50 = 4.75 M), likely attributed to the lipophilicity of halogen atoms and their capacity to form hydrogen bonds (Figure 1f) displayed sub-10 M IC 50 values against multiple cancer cell lines ( 2.3.2 Glycosylation Glycosylation of caudatin and its analogs exerts a significant impact on their anticancer activity, with the structural features of sugar moieties playing a pivotal role
