    A Screening Library for Peptide Activated G-Protein Coupled Receptors. 1. The Test Set

    No full text
    One subset of the G-protein coupled receptor (GPCR) superfamily is that which is activated by a peptide carrying an obligatory positively charged residue (GPCR−PA+). This subclass is exemplified by receptors for melanocortins, GnRH, galanin, MCH, orexin, and some chemokine receptors variously involved in eating disorders, reproductive disorders, pain, narcolepsy, obesity, and inflammation. Using the methods described in this study, a region of chemical property space enriched in GPCR ligands was identified. This information was used to design and synthesize a “test” library of 2025 single, pure compounds to sample portions of this property space associated with GPCR−PA+ ligands. The library was evaluated by high-throughput screening against three different receptors, rMCH, hMC4, and hGnRH, and found to be highly enriched in active ligands (4.5−61-fold) compared to a control set of 2024 randomly selected compounds. In addition, the analysis suggested that about 7000 compounds will be necessary to complete the sampling of this GPCR−PA+ ligand-rich region and to better define its borders

    The economic costs of weeds on productive land in New Zealand

    No full text
    Here we review published research on the costs of weeds to New Zealand’s pastoral, arable and forestry sectors, and propose an alternative dynamic approach for future research. The studies reviewed had little in common methodologically, often contained guesswork, or were outdated. Their aggregation resulted in a conservative estimate of the cost of weeds to New Zealand’s agricultural economy of 1658million(2014NZD).Toaddressdeficienciesinpreviouslyusedmethodologies,adynamicapproachisdevelopedandappliedtoacasestudyongiantbuttercupindairypastures.Thisapproachaccountsforprobabletemporalchangesinboththegeographicextentoftheweedandinproducerpricesandindicatesannuitizedcosts(overtheperiod20122030)of1658 million (2014 NZD). To address deficiencies in previously used methodologies, a dynamic approach is developed and applied to a case study on giant buttercup in dairy pastures. This approach accounts for probable temporal changes in both the geographic extent of the weed and in producer prices and indicates annuitized costs (over the period 2012–2030) of 166 million, 259millionand259 million and 592 million for rates of spread of 144, 60 and 20 years for giant buttercup to invade all dairy regions in New Zealand. Comparing the aggregate cost of all weeds to the three productive sectors estimated from the historical data with these ‘dynamic’ estimates for the one species in dairy pasture, indicates that the historical data provide a substantial underestimate of the true aggregate cost of weeds to New Zealand’s agricultural economy
