A series of Fe-doped Bi2(FexGa1-x)4O9 (x=0.1,0.2,0.3,0.4,0.5) ceramics were synthesized by solid-phase method with sintering process. The influences of Fe doping content on phase, morphology, dielectric properties are discussed. XRD results show that there is no second phase in Fe-doped Bi2(FexGa1-x)4O9 ceramics. The SEM analysis indicates the grain size of as-prepared doped samples are relatively uniform and estimated to be about 1–4μm. The permittivity of as-prepared doped samples increases and the dielectric loss decrease compared to pure Bi2Ga4O9 ceramics.

Fluorescent Analogues

Fluorescent analogues of vasotocin, [1-(beta-mercaptopropionic acid), 9-(p-aminofluoresceinylphenylalanine)]arginine vasotocin [[MPA1, (p-NH2flu)Phe9]AVT] and [1-(beta'-mercaptopropionic acid), 9-(p-amino rhodaminylphenylalanine)]AVT [[MPA1, (p-NH2rhod)-Phe9]AVT], were synthesized by the solid-phase method. These compounds yielded half-maximal hydrosmotic responses (half-maximal values) in the toad urinary bladder at 2 X 10(-9) M. Epifluorescence microscopy showed punctate basal localization of analogues on the majority of bladder epithelial cells within 20 min. The cellular localization was prevented by vasotocin. These fluorescent analogues may serve as useful probes for vasotocin receptors in toad bladder and in tissues from other species that use vasotocin as their antidiuretic-pressor hormone.

With the H2C2O4·2H2O and Mg(NO3)2·6H2O as the raw materials, nanometer-MgO powder was synthesized at different temperature by the low temperature solid phase method. After the characterization of the structure and property of this kind of nanometer-MgO powder with TG, XRD, SEM and FT-IR, etc, the antibacterial property of nanometer-MgO powder to Escherichia Coli and Staphylococcus Aureus was examined through the bacteriostatic circle method. The results indicated that the powder was single crystal, complete crystallization and uniform distribution with the 10 nm of particle size. It had better resistance and capacity of killing bacteria and the diameter of the bacteriostatic circle was greater than 19 mm.

Analogs of angiotensin II in which phenylalanine in position 8 was replaced with cymantrenylalanine or with its triphenylphosphine photosubstitution product were synthesized by the solid-phase method. On rabbit aorta strips, these peptides were found to be pure antagonists of angiotensin II. Their relative affinities are higher than most other analogs substituted in position 8 with bulky amino-acids.

Solid Phase Method

In an attempt to determine some of the structural features in position 1 that account for V1 antagonism, four new analogues of arginine-vasopressin were synthesized and the effect of the modifications on the vasoconstrictor activity was checked using isolated mesenteric arterial vessels of rats. The protected precursors required for these analogues were synthesized by a solid phase method of peptide synthesis. One of the reported analogues, namely [1-(4-mercapto-4-tetrahydrothiopyraneacetic acid)., 2-O-methyltyrosine, 8-arginine]vasopressin appears to be a potent competitive antagonist of the vasoconstrictor effect by AVP.

Inflammatory Effect

Two {Met(0)6}deacetyl-thymosin β4analogs containing Phe(4F) or Tyr(Me) at position 12 were synthesized by the manual solid-phase method, and their anti-inflammatory effect on carrageenin-induced edema in the mouse paw was studied. Fluorination of the para-position of Phe12resulted in a marked antiinflammatory effect on carrageenin-induced edema in the mouse paw compared with that of our synthetic {Met(0)6}deacetyl-thymosin β4, but the other analog, {Met(0)6, Tyr(Me)12}deacetyl-thymosin β4, showed a marked reduction of the anti-inflammatory effect.
