Figure 4 represents meridine docking on G-Quadruplex macromolecule. These points indicated meridine effectiveness to be considered as prominent anticancer PCNP molecule, where potential attachment positions of meridine for testing substituents could improve the anticancer activity by increasing the corresponding affinity for the target.
Do the challenges of inhaled insulin close the door on the opportunity for inhaled macromolecules, or the use of the lung as a portal for the delivery of any systemic acting pharmaceutical?
1) Attraction - One specialized component of the macromolecule enables strong hydrogen bonds with electrostatic interactions to attract the proteins on the virus surface - disabling viral ability to infect healthy cells.
A stepwise screening approach utilizing both in-vitro and in-vivo models was adopted to evaluate formulation candidates and so to overcome the permeability challenge of the macromolecule. These studies demonstrated that lipid formulations, made of GRAS ingredients, releasing under normal biological permeation enhancers showed superior performance to formulations evolving into nanoparticulate systems.
