Specifically, tobacco mosaic virus (TMV) and tobacco mild green mosaic virus (TMGMV) are developed as drug carriers that encapsulate the monocationic, dicationic, tricationic, and tetracationic versions of a porphyrin‐based photosensitizer drug (Zn‐Por). While TMV has been extensively explored for various nanotechnology applications, this is the first study investigating TMGMV for medical applications. Light‐activated cancer cell killing of Zn‐Por‐loaded VNPs is studied in vitro using melanoma and cervical cancer models. Native and nucleolin‐targeted VNP drug carriers are developed and their efficacy assessed. A fivefold increase in cancer cell killing is observed using nucleolin‐targeted TMV loaded with tricationic Zn‐Por and displaying the nucleolin‐specific F3 peptide.}, number={5}, journal={Macromolecular Bioscience}, publisher={Wiley}, author={Chariou, Paul L. and Wang, Lu and Desai, Cian and Park, Jooneon and Robbins, Leanna K. and Recum, Horst A. and Ghiladi, Reza A. and Steinmetz, Nicole F.}, year={2019}, month={Feb}, pages={1800407} } @article{robbins_lilly_sommer_ison_2016, title={Effect of the Ancillary Ligand on the Mechanism for CO Migratory Insertion in High-Valent Oxorhenium Complexes}, volume={35}, ISSN={["1520-6041"]}, DOI={10.1021/acs.organomet.6b00570}, abstractNote={Several oxorhenium complexes bearing an SSS pincer ligand were isolated and characterized, and their reactivity with carbon monoxide was explored.

The mechanism for carbonylation was explored with DFT (M06) calculations and revealed that the most likely mechanism for carbonylation involved stepwise formation of CO adducts followed by migration of the carbonyl ligand to the alkyl/aryl groups.}, number={20}, journal={ORGANOMETALLICS}, publisher={American Chemical Society (ACS)}, author={Robbins, Leanna K. and Lilly, Cassandra P. and Sommer, Roger D. and Ison, Elon A.}, year={2016}, month={Oct}, pages={3530–3537} } @article{lambic_lilly_robbins_sommer_ison_2016, title={Reductive Carbonylation of Oxorhenium Hydrides Induced by Lewis Acids}, volume={35}, ISSN={["1520-6041"]}, DOI={10.1021/acs.organomet.6b00393}, abstractNote={Several oxorhenium hydride complexes with chelating diamidopyridine (DAP), diamidoamine (DAAm), and 2-mercaptoethyl sulfide (SSS) groups have been isolated and characterized.

CO insertion into the Re–R bond in 1 and 3a–d resulted in the formation of the acetyl complex, 2, and the (aryl)acetyl complexes, 5a–d respectively. The formation of 5a–d proceeded at a faster rate (7 h) than the formation of 2 (72 h) under the same conditions. No reaction was observed however for the phenyl complex 4 with CO. Kinetics for CO insertion into the various Re–R bonds were examined, and the experimental rate law was determined to be Rate = kobs[Re][CO]. The activation parameters for CO insertion into 1 and 3a were determined to be ΔG⧧(298 K) = 24(1). The enthalpy of activation ΔH⧧ was determined to be 9(1) and 10(3) kcal/mol for 1 and 3a, respectively, and the entropy of activation, ΔS⧧, was −49(2) and −36(4) cal/mol·K.
