Synthesis, Characterization and Kinetic Release Profile of Iron Containing Polymeric Co-conjugates with Antiproliferative Activity

Dissolvable wound dressing loaded with silver nanoparticles together with ampicillin and ciprofloxacin

Aim: The current study is focused on the development of water-soluble wound dressings, which are potential dressings for the treatment of burn wounds. Materials & methods: Sodium alginate-based dissolvable wound dressings were prepared and loaded with silver nanoparticles and various antibiotics (ampicillin and ciprofloxacin) followed by characterization and in vitro antibacterial studies. Results & conclusions: The prepared sodium alginate-based dissolvable wound dressing exhibited good porosity, water uptake and moisture content, promising antibacterial activity, high absorption capacity of simulated wound exudates, excellent water vapor transmission rate in the range of 2000 to 5000 g/m² day^-1, sustained drug-release profiles and water solubility. The wound dressings were active against Proteus mirabilis, Staphylococcus aureus, Proteus vulgaris, Escherichia coli and Klebsiella aeruginosa strains of bacteria. The results obtained revealed the wound dressing as potential wound dressings for burn wounds and sensitive skin.

Macromolecular Prodrugs Containing Organoiron-Based Compounds in Cancer Research: A Review

Among the methods used for the treatment of cancer, chemotherapy is widely used, and it is by far one of the most unpleasant procedures given to a patient because of its severe side effects; while being necessary. One of the major problems in cancer chemotherapy is the limited selectivity of most of the drugs in current clinical use. Following administration, the active agent is distributed over the entire body and reaches not only the target cells or tissues but also interacts with healthy cells. In an attempt to overcome the side effects of anticancer drugs, the modification of the anticancer bioactive compounds has been a topic of active research for years. Numerous delivery systems such as drugcontaining liposomes, microencapsulation, nanoparticles, and water-soluble polymers have been used for the delivery of bioactive compounds to the site of action. Water-soluble polymeric conjugates and co-conjugates have remained the most outstanding delivery technique. This review will discuss the development of polymeric conjugates and co-conjugates of ferrocene in cancer research.
