, p. 1871 - 1874 (1983)
A diamine oxidase (DAO) (EC 1.4.3.6) has been purified to homogeneity from lentil seedlings.The purified protein has a MW of 154000 and is composed of two apparently identical subunits.It contains two Cu(2+) atoms and one carbonyl-like group per mol.The purified enzyme is pink-red in concentrated solution and shows a broad, well-defined, absorption band in the visible region centered at 498 nm.The ESR spectrum is typical of Cu(2+) in a tetragonal symmetry.The enzyme oxidizes only aliphatic diamines and spermidine with formation of the corresponding aldehydes, hydrogen peroxide and ammonia.Putrescine and cadaverine are oxidized most rapidly and the oxidation rate decreases when longer diamines are tested. - Key Word Index - Lens esculenta; Leguminosae; lentil seedlings; copper protein; diamine oxidase.

A series of quinazoline derivatives with benzylidene hydrazine carboxamide were designed and synthesised as EGFR inhibitors. Most compounds exhibited exceptional anti-proliferative activity against A549, HepG2, MCF-7 and H1975 cells. Furthermore, six compounds demonstrated excellent inhibition activity against EGFRWT with the IC50 value both less than 2 nM. Among the six compounds, 44 exhibited the strongest activity (0.4 nM) and potently inhibited EGFRL858R/T790M (0.1 μM). Excitingly, the most potent compound 14 showed excellent enzyme inhibitory activity with 6.3 nM and 8.4 nM for both EGFRWT and EGFRT790M/L858R. The result of AO single staining and Annexin V/PI staining showed that the compound 14 and 44 could induce remarkable apoptosis of A549 cells. The compound 14 arrested the cell cycle at the S phase and compound 44 arrested the cell cycle at the G0 phase in A549 cells. These preliminary results demonstrate that compound 14 and 44 may be promising lead compound-targeting EGFR.
Water-soluble red-emitting distyryl-borondipyrromethene (BODIPY) dyes for biolabeling

A series of water-soluble red-emitting distyryl-borondipyrromethene (BODIPY) dyes were designed and synthesized by using three complementary approaches aimed at introducing water-solubilizing groups on opposite faces of the fluorescent core to reduce or c
