Weed control remains one of the greatest problems in agro-ecological systems. An important factor controlling crop and weed competition for below ground resources is the presence of compacted soil layers or ‘hard pans’. In a series of experiments, we investigated the ability of roots of soybean (Glycine max L.) and the weeds sicklepod (Senna obtusifolia L.)(More)
Fialuridine (FIAU) is a halogen-substituted analog of thymidine that was undergoing clinical investigation as a drug for the treatment of chronic hepatitis B viral infection. However, clinical trials of FIAU were terminated after adverse events occurred following chronic oral administration. Prior to the termination of clinical trials, a sensitive assay was(More)
Glucagon-like insulinotropic peptide (GLP-1) and its analogs are of interest because of their therapeutic potential in type II diabetes. LY315902 is a GLP-1-(7-37)-OH analog with a modified N-terminus (IP7), an octanoic acid (C8) acylated on the lysine residue at position 34, and a substitution with arginine at position 26. We developed a sensitive and(More)
LY309887, a reduced analogue of folic acid, is a potent inhibitor of glycinamide ribonucleotide formyltransferase and possesses a broad spectrum of antitumor activity. During preclinical studies using supplementation with oral folic acid, this second-generation inhibitor displayed both the desired safety profile and the pharmacology to warrant clinical(More)
