The Qinghai-Tibetan Plateau (QTP) is the highest and one of the most extensive plateaus in the world. Phylogenetic, phylogeographic, and ecological studies support plant diversifications on the QTP through multiple mechanisms such as allopatric speciation via geographic isolation, climatic oscillations and divergences, pollinator-mediated isolation, diploid(More)
Angiotensin II receptor blockers (ARB) are widely used drugs that are proven to reduce cardiovascular disease events; however, several recent meta-analyses yielded conflicting conclusions regarding the relationship between ARB and cancer incidence, especially when ARB are combined with angiotensin-converting enzyme inhibitors (ACEI). We investigated the(More)
The inclusion complexation of Epothilone A with native cyclodextrin (β- or γ-CD) and its derivative hydroxypropyl-β-cyclodextrin (HPβCD) were prepared. Their behavior, characterization, and binding ability were investigated in both solution and the solid state by means of UV-vis, NMR, XRD, DSC and SEM. The results show that the water solubility and solution(More)
DNA barcoding, the identification of species using one or a few short standardized DNA sequences, is an important complement to traditional taxonomy. However, there are particular challenges for barcoding plants, especially for species with complex evolutionary histories. We herein evaluated the utility of five candidate sequences - rbcL, matK, trnH-psbA,(More)
The evolution and current distribution of the Sino-Tibetan flora have been greatly affected by historical geological events, such as the uplift of the Qinghai-Tibetan Plateau (QTP), and Quaternary climatic oscillations. Rhodiola kirilowii, a perennial herb with its distribution ranging from the southeastern QTP and the Hengduan Mountains (HM) to adjacent(More)
Vascular endothelial growth factor receptor-2 (VEGFR-2) kinase inhibition is a well-established strategy to promptly tackle tumor growth by suppression of angiogenesis. We report herein a series of 5-anilinoquinazoline derivatives substituted by 1,3-disubstituted urea. All the newly synthesized compounds described were evaluated for VEGFR-2 kinase(More)
