Doxorubicin is the most common chemotherapy drug used in cancer therapy. Its usage is associated with various side-effects. In order to overcome the challenges in Doxorubicin administration, the present study has focussed on synthesizing a drug conjugate with biosynthesized gold nanoparticles and doxorubicin. The gold nanoparticles were biosynthesized using green extracts of medicinal plants with potential anticancer activities. The nanoparticle that possesses anticancer activity was conjugated with the drug for a combinatorial effect of the nanoparticles and the drug. The in vitro cytotoxicity was checked in Vero cell line through MTT assay. The in vitro anti proliferative effects were screened against cervical cancer in HeLa cell line. Fluorescence activated cell sorting analysis was carried out to detect the difference between live and dead cell populations. The preliminary confirmation was carried out in UV-VIS spectrophotometer. The morphological characterization was carried out by SEM and stability by Zeta potential. The IC50 of the nanocompounds demonstrated anti-proliferative activity against cervical cancer similar to the chemotherapeutic drug, Doxorubicin; additionally in a much lesser concentration of the drug. The in vitro cytotoxicity exhibited high viability of cells in Vero cell line with minimum viability of 80% in all the tested concentrations. There was a synergistic effect of the nanoparticles along with the drug; thereby an enhanced therapeutic efficiency was achieved. FACS analysis showed 36% of cell death in Dox treated HeLa cells whereas 96% of cell death in Nano-Dox treated HeLa cells. Nano-Dox conjugate has demonstrated high anticancer effects than drug alone Doxorubicin. Further biosynthesized nanomaterials based drug formulation can be developed as a potential strategy in cancer therapy.

This study aimed to investigate the anticancer activity of Haplophyllum tuberculatum(Forsk.) aerial parts ethanol extract and fractions and reveal the potential anticancer targets, binding modes, pharmacokinetics, and toxicity properties of its phytoconstituents. MTT assay was used to investigate the anticancer activity. TargetNet, ChemProt version 2.0, and CLC-Pred web servers were used for virtual screening, and Cresset Flare software was used for molecular docking with the 26 predicted targets. Moreover, pkCSM, swiss ADME, and eMolTox web servers were used to predict pharmacokinetics and safety. Ethanolic extracts of H. tuberculatum on HepG2 and HeLa cell lines showed promising activities with IC50 values 54.12 and 48.1 µg/mL, respectively. Further, ethyl acetate fraction showed the highest cytotoxicity on HepG2 and HeLa cell lines with IC50 values 41.7 and 52.31 µg/mL. Of 70 compounds screened virtually, polygamain, justicidin A, justicidin B, haplotubine, kusunokinin, and flindersine were predicted as safe anticancer drugs candidates. They showed the highest binding scores with targets involved in cell growth, proliferation, survival, migration, tumor suppression, induction of apoptosis, metastasis, and drug resistance. Our findings revealed the potency of H. tuberculatum as a source of anticancer candidates that further studies should support.

Radiolabeled gold nanoparticles (AuNPs) have been widely used for cancer diagnosis and therapy over recent decades. In this study, we focused on the development and in vitro evaluation of four new Au nanoconjugates radiolabeled with technetium-99m (99mTc) via thiol-bearing ligands attached to the NP surface. More specifically, AuNPs of two different sizes (2 nm and 20 nm, referred to as Au(2) and Au(20), respectively) were functionalized with two bifunctional thiol ligands (referred to as L1H and L2H). The shape, size, and morphology of both bare and ligand-bearing AuNPs were characterized by transmission electron microscopy (TEM) and dynamic light scattering (DLS) techniques. In vitro cytotoxicity was assessed in 4T1 murine mammary cancer cells. The AuNPs were successfully radiolabeled with 99mTc-carbonyls at high radiochemical purity (>95%) and showed excellent in vitro stability in competition studies with cysteine and histidine. Moreover, lipophilicity studies were performed in order to determine the lipophilicity of the radiolabeled conjugates, while a hemolysis assay was performed to investigate the biocompatibility of the bare and functionalized AuNPs. We have shown that the functionalized AuNPs developed in this study lead to stable radiolabeled nanoconstructs with the potential to be applied in multimodality imaging or for in vivo tracking of drug-carrying AuNPs.
