Syntheses of novel 1,3-diazaazulene derivatives and their nonlinear optical characterization

We have synthesized three new 1,3-diazaazulene derivatives, namely, 2-(4′-N,N-dimethylaminophenyl)-6-nitro-1,3-diazaazulene (18, DMAPNA), 2-(4′-aminophenyl)-6-nitro-1,3-diazaazulene (19, APNA) and 2-[4′-N-(2-hydroxyethyl)aminophenyl]-6-nitro-1,3-diazaazulene (20, HEAPNA), each of them contains an amino substitute as the electron donor (D), 2-phenyl-1,3-diazaazulene as the π-conjugated bridge and a nitro as the electron acceptor (A). Our theoretical results have predicted that these D-π-A type chromophores possess low ground-state dipole moment (μg) and large first-order hyperpolarizability (β), which may facilitate a low degree of aggregation for the chromophores dispersed in a polymeric matrix as well as a large nonlinear optical (NLO) response. The expected NLO performance has been confirmed by the experimental β and μg values, e.g., for 18, 407.8 × 10-30 esu and 4.7 D, respectively. The origins of large β and low μg are explained in terms of a two-state quantum model. The DMAPNA (18)-doped and poled polymethylmethacrylate film exhibits a large second harmonic generation (SHG) coefficient of d33 = 10.9 pm V-1 with excellent thermal stability (above 70% of the maximal SHG coefficient remains at ～100 °C).

Design, synthesis and structure-activity relationships of novel diaryl urea derivatives as potential EGFR inhibitors

Two novel series of diaryl urea derivatives 5a-i and 13a-l were synthesized and evaluated for their cytotoxicity against H-460, HT-29, A549, and MDA-MB-231 cancer cell lines in vitro. Therein, 4-aminoquinazolinyl-diaryl urea derivatives 5a-i demonstrated significant activity, and seven of them are more active than sorafenib, with IC50 values ranging from 0.089 to 5.46 μM. Especially, compound 5a exhibited the most active potency both in cellular (IC50 = 0.15, 0.089, 0.36, and 0.75 μM, respectively) and enzymatic assay (IC50 = 56 nM against EGFR), representing a promising lead for further optimization.

Styrylamidines

Styrylamidines are prepared by treating styrylsulfonylamidines with base. The styrylamidines are effective in the prevention of aggregation of blood platelets and as analgesics. Compounds of the invention are also useful as anticonvulsants, diuretics and antihypertensive agents. The styrylsulfonylamidines of the invention which serve as precursors to the styrylamidines also have analgesic properties. Illustrative of the styrylamidines of the present invention are 4-amino-N-(4-aminostyryl)benzamidine and N-(3,4-dichlorostyryl)acetamidine. An example of a styrylsulfonylamidine is N-(styrylsulfonyl)acetamidine.
