Abstract:
Diselenide-bond-linked poly(N-isopropylacrylamide)-paclitaxel chemical conjugates are synthesized as a drug release carrier. The conjugates can self-assemble into "core-shell" nanoscaled micelles in aqueous solution and show thermal and redox dual-responsiveness. The conjugates can afford a high encapsulation efficiency of up to 72.3%, and deliver hydrophobic anticancer drug paclitaxel in a temperature and oxidization or reduction stress-mode. The in vitro 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) and in vivo anticancer assays are performed to assess the cytotoxicity and anticancer activity of the conjugates, suggesting that the developed conjugates can be used to treat carcinoma as a novel and highly efficient drug delivery system.

Conjugated Proteins
Nucleoproteins are protein complexes that contain nucleic acids, categorized as deoxyribonucleoproteins (DNPs) or ribonucleoproteins (RNPs) respectively. The nucleosome is a typical example of a DNP where nuclear DNA is associated with histone proteins. The major antigen for the Covid-19 virus SARS-CoV is an RNP that is critical...
