#1: "Organocatalytic Direct Asymmetric Aldol Reactions in Water," by Nobuyuki Mase, Yusuke Nakai, Naoko Ohara, Hidemi Yoda, Kunihiko Takabe, Fujie Tanaka, and Carlos F. Barbas III, J. Am. Chem. Soc.; 2006; 128(3) pp 734 – 735. #4: "Direct Asymmetric anti-Mannich-Type Reactions Catalyzed by a Designed Amino Acid," by Susumu Mitsumori, Haile Zhang, Paul Ha-Yeon Cheong, K. N. Houk, Fujie Tanaka, and Carlos F. Barbas, III, J. Am. Chem. Soc.; 2006; 128(4) pp 1040 – 1041. #7: "Organocatalytic Direct Michael Reaction of Ketones and Aldehydes with b-Nitrostyrene in Brine," by Nobuyuki Mase, Kaori Watanabe, Hidemi Yoda, Kunihiko Takabe, Fujie Tanaka, and Carlos F. Barbas III, J. Am. Chem. Soc.; 2006; 128(15) pp 4966 – 4967. Along with online publication in the Journal of the American Chemical Society, the articles are now featured on "The Most," a website featuring the most-cited, most-accessed, and "hottest" articles from ACS Publications, as reported by Thomson ISI's Web of Science.
Griffin developed the image as part of a project using an automated microscopic platform to identify small compounds that alter biochemical and morphological parameters in cellular context. This technology, called "high content screening," combines relatively high compound throughput with single cell analysis and is an early part of modern drug discovery. The Translational Research Institute of Scripps Florida routinely uses high content screening for functional analysis of high throughput screening and Med Chem leads. The image shows NIH-3T3 fibroblasts that overexpress the gene src, a family of proto-oncogenes that may lead to cancer. Src overexpression results in actin re-localization toward structures known as "podosomes," which are thought to be involved in cell motility. See the In Cell Competition web site for more information on the contest.
