plantago cordata/tyrosine

Plasiatine (1), isolated from the seeds of Plantago asiatica, is an unprecedented indole analogue linked to a phenylpropanoid moiety via a carbon bond that builds up a novel heteromeric construction with a C19N2 scaffold. Its structure was determined by spectroscopic data and computational evidence.

Tyrosine kinase inhibition and tumor growth inhibition activity of verbascoside and homoplantaginin are described. Both molecules proved to be equally significant inhibitors of isolated EGF-R tyrosine kinases, nevertheless their in vitro antiproliferative activity was variable in cellular assays.

Increasing interest in the ability of plants to take up amino acids has given rise to questions on the accuracy of the commonly used bulk method to measure and calculate amino acid uptake. This method uses bulk measurements of 13C and 15N enrichment in plant tissues after application of

Plantaginis semen, the dried mature seed of Plantago asiatica L. or Plantago deprdssa Willd., has a prominent effect on the treatment of obesity, type 2 diabetes and lipid disorders, however, its clinical application is limited due to inadequate in-depth mechanism exploration and incomplete
