PorphyrinViLiGe™

The PorphyrinViLiGe™ program was developed to simulate combinatorial processes and to enumerate products and isomers in the domain of porphyrins (and other tetrapyrrole macrocycles) via virtual library generation.  The program was conceived, developed and tested by Drs. Masahiko Taniguchi, Hai Du, and Jonathan S. Lindsey from Summer 2010 – Summer 2011.

The program and results have been described:
"Virtual Libraries of Tetrapyrrole Macrocycles. Combinatorics, Isomers, Product Distributions, and Data Mining,"
Taniguchi, M.; Du, H.; Lindsey, J. S. J. Chem. Info. Model. 2011, 51, 2233–2247.

The program has been applied in one example concerning prebiotic chemistry:
"Tandem Combinatorial Model for the Prebiogenesis of Diverse Tetrapyrrole Macrocycles,"
Taniguchi, M.; Soares, A. R. M.; Chandrashaker, V.; Lindsey, J. S. New J. Chem. 2012,  36, 1057–1069.

New terminology was recently introduced to delineate isomers within combinatorial libraries:
"Diversity, Isomer Composition, and Design of Combinatorial Libraries of Tetrapyrrole Macrocycles,"
Taniguchi, M.; Lindsey, J. S. J. Porphyrins Phthalocyanines 2012, 16, 1–13.

A lengthy review concerning tetrapyrrole isomers has been prepared:
"Enumeration of Isomers of Substituted Tetrapyrrole Macrocycles: From Classical Problems in Biology to Modern Combinatorial Libraries,"
Taniguchi, M.; Lindsey, J. S. in Handbook of Porphyrin Science; Kadish, K. M.; Smith, K. M.; Guilard, R., Eds.; World Scientific: Singapore, 2012, Vol. 23, pp. 1–80.
