The most widely used viral capsids include the protein cage of the cowpea mosaic virus (CPMV), cowpea chlorotic mottle virus (CCMV), and MS2 bacteriophage. The application of viral capsids in targeted drug delivery and diagnostic imaging has been demonstrated over the past few decades.

Apart from simple disassembly/reassembly of the viral capsid, drug cargo can also be loaded through covalent attachment of drugs or their analogs to certain reactive moieties on the capsid proteins. Moreover, residues can also be site-specifically engineered into the capsid protein to …Author: Y. Ma, Y. Ma, R.J.M. Nolte, Jeroen Johannes Lambertus Maria Cornelissen

A targeted drug delivery vehicle based on the bacteriophage MS2 viral capsid was constructed using site-selective bioconjugation reactions. A palladium-catalyzed tyrosine allylation reaction was evaluated for interior modification of intact MS2 capsids with water-insoluble drug molecules.Author: Wesley Wu

Catechol ligands are chemically attached to the interior surface of P22 viral capsid for subsequent encapsulation of an anticancer drug, bortezomib (BTZ), through boronic acid‐diol complexation. For targeted delivery, hepatocellular carcinoma (HCC)‐targeting peptide (SP94, SFSIIHTPILPL) is synthesized and chemically conjugated to the exterior surface of the P22 viral capsid nanocomposites.Author: Junseon Min, Hyojin Moon, Hyun Ji Yang, Hyun‐Hee Shin, Sung You Hong, Sebyung Kang

The capsid protein assembles in E. coli after recombinant expression, 16 yielding non-infectious genome-free particles with adjustable amino acid composition. The capsid structure is inherently monodisperse, an important advantage for the controlled biodistribution of drug delivery vehicles.Author: Wesley Wu, Sonny C. Hsiao, Zachary M. Carrico, Matthew B. Francis

Jan 19, 2017 · An alternate type of drug delivery NP that is showing promise is the VLP. 20 VLPs are self‐assembled, homogeneous NPs derived from the coat proteins of viral capsids. They typically lack their natural genome and are therefore noninfectious.Author: Marcus J. Rohovie, Maya Nagasawa, James R. Swartz

With the development of covalent modification strategies for viral capsids comes the ability to convert them into modular carrier systems for drug molecules and imaging agents. With this overall goal in mind, we have used two orthogonal modification strategies to decorate the exterior surface of genome-free MS2 capsids with PEG chains, while installing 50−70 copies of a fluorescent dye inside as a drug cargo …Author: Ernest W.
