Background: Phenylpropylene biosynthesis pathway plays a crucial role in the vanillin and their derivative(s) production in the plants. The intermediate of vanillin synthesis i.e. cinnamic acid (CA) is converted into 2-Hydroxy 4-MethoxyBenzaldehyde (HMB) in Decalepis arayalpathra having a number of therapeutic value. Objective : Microwave-assisted modifications in cinnamic acid were planned for potential anticancer properties with better yield and efficiency. The present study also confirms the presence of HMB and its precursor i.e. cinnamic acid in D. arayalpathra tubers. Methods: We used a single step Microwave Assisted Synthesis (MAS) to modify cinnamic acid, and then examined the synthetic and natural cinnamic acid derivatives anticancer potential against six human cancer (K-562, WRL-68, A549, A431, MCF-7, and COLO-201) and two normal (L-132 and HEK-293) cell lines at 2, 10 and 50 µg/ml concentrations. Results: β-bromostyrene and β -nitrostyrene have shown inhibition with IC50 values ranging 0.10-21 µM and 0.03-0.06 µM, respectively to the cancer cell lines. β-bromostyrene was the most potent anticancer derivative of CA with better cellular safety and biocompatibility. Conclusions: The present study of microwave-assisted synthesis demonstrates a single-step modification in cinnamic acid. MAS is a fast, reliable, and robust method. The resultant compounds have shown in-vitro anticancer activity against human lung carcinoma and breast adenocarcinoma.

Microwave assisted synthesis technique was used to prepare palladium supported on iron oxide nanoparticles. The advantage of using microwave irradiation as a synthetic tool is due to its unique features as a one step, simple, versatile, and rapid process. The reactants are added simply at room temperature without using high-temperature injection. Hydrazine hydrate was added by the following ratios (0.1, 0.2, 0.3, 0.4, 0.6, 0.8, 1, 1.6, and 3) ml to the different prepared samples at room temperature in order to investigate its effect on the catalytic performance of the prepared catalysts. The prepared catalyst could be used as an ideal candidate not only for Pharmaceutical industry through cross-coupling reactions but also for low temperature oxidation catalysis of carbon monoxide and pharmaceutical applications as well. The experimental results showed that Pd/Fe3O4 catalyst has a remarkable catalytic activity for carbon monoxide oxidation catalysis due to the strong interaction between palladium and iron oxide nanoparticles. This may be due to the small particle size (7-14 nm) and concentration ratio of the Pd nanoparticles dispersed on the surface of magnetite (Fe3O4). Those nanoparticles were characterized by various spectroscopic techniques including; X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), Vibrating Sample Magnetometer (VSM) and transmission electron microscopy (TEM).

Uniform iron oxide magnetic nanoparticles have been synthesized using a microwave assisted synthesis method in organic media and their colloidal, magnetic, and relaxometric properties have been analyzed after its transference to water and compared with those nanoparticles prepared by thermal decomposition in organic media. The novelty of this synthesis relies on the use of a solid iron oleate as precursor, which assures the reproducibility and scalability of the synthesis, and the microwave heating that resulted in being faster and more efficient than traditional heating methods, and therefore it has a great potential for nanoparticle industrial production. The effect of different experimental conditions such as the solvent, precursor, and surfactant concentration and reaction time as well as the transference to water is analyzed and optimized to obtain magnetic iron oxide nanoparticles with sizes between 8 and 15 nm and finally colloids suitable for their use as contrast agents on Magnetic Resonance Imaging (MRI). The r2 relaxivity values normalized to the square of the saturation magnetization were shown to be constant and independent of the particle size, which means that the saturation magnetization is the main parameter controlling the efficiency of these magnetic nanoparticles as MRI T2-contrast agents.
