Synthesis of Quinazolin-4(3<i>H</i>)‑ones via Amidine <i>N</i>‑Arylation
PyridoÂ[4,3-<i>d</i>]Âpyrimidin-4Â(3<i>H</i>)-one
(<b>1</b>) was prepared by reacting 2-trifluoromethyl-4-iodo-nicotinic
acid (<b>2</b>) with amidine <b>9a</b> catalyzed by Pd<sub>2</sub>(dba)<sub>3</sub> and Xantphos, followed by cyclization effected
with HBTU and subsequent demethylation using PhBCl<sub>2</sub>. The
amidine arylation method was found applicable for the syntheses of
quinazolin-4Â(3<i>H</i>)-ones. Thus, reaction of 2-bromo
or 2-iodo benzoate esters with amdidines afforded substituted quinazolin-4Â(3<i>H</i>)-ones in 44–89% yields
The effect of high-fat diet on the plasma lipidome.
<p>Significant mean fold changes (P<0.05) observed in plasma lipids from mice fed a high fat diet for 12 week (N = 6) relative to low fat fed animals (N = 8). Plasma lipids were analysed by LC ESI-MS/MS and absolute lipid levels were expressed relative to the low fat fed control group. Plasma samples were obtained from 5 hour fasted animals. BMP, bismonoacylglycerolphosphate; Cer, ceramide; DG, diacylglycerol; DHC, dihexosylceramide; LPC, lysophosphatidylcholine; MHC, monohexosylceramide; PC, phosphatidylcholine; PE, phosphatidylethanolamine; PG, phosphatidylglycerol; SM, sphingomyelin; Sph, sphingosine; TG, triacylglycerol; THC, trihexosylceramide.</p
Time course changes in metabolic parameters measured in mice fed a high fat diet.
<p>Body mass (A), fat mass (B), fasting blood glucose (C), plasma insulin (D), blood glucose during an intraperitoneal glucose tolerance test (E) and blood glucose area under the curve during an intraperitoneal glucose tolerance test (F) were measured in mice (N = 11) following a 5 hour fast at baseline (time 0) and after 1, 3 and 6 weeks of high fat feeding. Data are presented as mean ± SEM. *P<0.05 versus baseline; <sup>†</sup>P<0.05 versus week 1; <sup>‡</sup>P<0.05 versus week 3.</p
Tissue lysophosphatidylcholine levels in low and high fat fed mice.
<p>Liver (A), skeletal muscle (B) and adipose tissue (C) lysophosphatidylcholine (LPC) levels measured by LC ESI-MS/MS in mice fed a low (N = 8) or high fat diet (HFD, N = 6). Tissues were collected from 5 hour fasted animals. Data are presented as mean ± SEM. *P<0.05 versus low fat.</p

Relationship between plasma lysophosphatidylcholine (LPC), adiposity and indices of insulin resistance in high fat fed mice (A–D) and lean, obese and obese type 2 diabetic humans (E–H).
<p>The association between circulating LPC and percent body fat (A), blood glucose (B), plasma insulin (C) and HOMA-IR (D) in high fat fed mice. The association between circulating LPC and BMI (E), blood glucose (F), plasma insulin (G) and HOMA-IR (H) in the human cohort. Data are presented as line of best fit with 95% confidence intervals.</p
