Abstract
Nanoparticles for a specific delivery are likely to be designed for cancer therapeutic effectiveness and improvement. In this study, a fucoidan-oleic acid conjugate was prepared and investigated in terms of loading capacity for poorly water-soluble anti-cancer drugs to maximize effectiveness of the treatment. Fucoidan was used as a hydrophilic portion of an amphiphilic structure for improving cancer therapeutic effects. Paclitaxel and curcumin were chosen as other model drugs loaded in the conjugates. The results showed that self-assembled nanoparticles with different sizes and morphologies could be prepared with two different concentrations of oleic acid as hydrophobic portion. Moreover, loading efficiency and release patterns of these drugs were mainly dependent on the hydrophobic interaction between drugs and oleic acid. It was also revealed that fucoidan and curcumin were released higher at pH 4.5 than at the physiological condition (pH 7.4), thus, facilitating the delivery and maximizing effects of the anticancer agents on cancer cells. On the contrary, paclitaxel from fucoidan nanoparticles was released faster at pH 7.4. The exploration of fucoidan–oleic acid conjugate could be considered as promising nanomedicines for cancer therapeutics.
Keywords: Fucoidan, conjugate, micelle, cancer therapeutics, nanomedicine.

Discovery of Lead compounds targeting transcriptional regulation
Transcriptional regulation plays key physiological functions in body growth and development. Transcriptional dysregulation is one of the important biomarkers of tumor genesis and progression, which is involved in regulating tumor cell processes such as cell proliferation, differentiation, and apoptosis. Additionally, it plays a pivotal role in angiogenesis and promotes tumor ...read more
Induction of cell death in cancer cells by modulating telomerase activity using small molecule drugs
Telomeres are distinctive but short stretches present at the corners of chromosomes that aid in stabilizing chromosomal makeup. The resynthesis of telomeres is supported by the activity of reverse transcriptase ribonucleoprotein complex telomerase. There is no telomerase activity in human somatic cells, but the stem cells and germ cells undergo ...read more
