He observed the same lack of diastereoselectivity in the formation of the C38 center observed by Molinski and Leahy,2 ascertained the viability of the hetero-Diels–Alder approach to the pyrans and established the feasibility of the Still–Gennari macrocycli- zation. Before 2006, Evans had ...
The combined organic extracts were washed with H2O The Journal of Antibiotics Synthesis of C-ring precursor of paclitaxel from 3-methoxytoluene K Fukaya et al 278 and brine, dried over Na2SO4 and concentrated. The residue was purified by silica-gel column chromatography (EtOAc/hexane 1:4–2:...
Thiazacridine and imidazacridine derivatives have shown promising results as tumors suppressors in some cancer cell lines. For a better understanding of the mechanism of action of these compounds, binding studies of 5-acridin-9-ylmethylidene-3-amino-2-thioxo-thiazolidin-4-one, 5-acridin-9-yl...

significantly associated with cardiovascular events and mortality rate [154,278,279]. If plasma BNP or NT-proBNP levels do not fall off after the therapies for HF, patients with HF have more hospital admission and higher mortality rate. In patients with HF, NT-proBNP has higher levels, better...
