The second edition of The Biomarker Guide is a fully updated and expanded version of this essential reference. Now in two volumes, it provides a comprehensive account of the role that biomarker technology plays both in petroleum exploration and in understanding Earth history and processes. Biomarkers and Isotopes in the Environment and Human History details the origins of biomarkers and introduces basic chemical principles relevant to their study. It discusses analytical techniques, and applications of biomarkers to environmental and archaeological problems. The Biomarker Guide is an invaluable resource for geologists, petroleum geochemists, biogeochemists, environmental scientists and archaeologists.

Advances in the chemistry of tetrahydroquinolines.

Novel pyrrolidine monomers bearing various functional groups are used to prepare oligomeric structures. The pyrrolidine monomers can be joined via standard phosphate linkages including phosphodiester, phosphorothioate, and phosphoramidate linkages. Useful functional groups include nucleobases as well as polar groups, hydrophobic groups, ionic groups, aromatic groups and/or groups that participate in hydrogen-bonding,

An analytical method has been developed for the assignment of recent and archaeological wood tar pitches to the species of trees used for their preparation. It incorporates the prepurification by Kugelrohr distillation and solid-phase extraction followed by gas chromatography/mass spectrometry analysis. Distribution patterns of volatile, thermostable triterpenoids and steroids characterizing the biological origin of the pitches are evaluated vy principal component analysis (PCA) and discriminant component analysis (DCA) of the data.

Identification of archaeological and recent wood tar pitches using gas chromatography/mass spectrometry and pattern recognition

The synthesis of three substituted 6,7-dihydroxy-4-quinazolineamines: tandutinib (1), erlotinib (2) and gefitinib (3) in improved yields is reported. The intermediates were characterized by NMR and the purities determined by HPLC.
