  摘要：

  Two novel handles for peptide amide preparation under mild conditions were developed for use in highly efficient solid-phase peptide synthesis. These handles, 5-{[(R,S)-5-[(9-fluorenylmethoxy-carbonyl)amino]-10,11-dihydrodibenzo[a,d]cyclohepten-2-yl]oxy}valeric acid (CHA) and 5-{[(R,S)-5-[(9-fluorenylmethoxycarbonyl)amino]dibenzo[a,d]cyclohepten-2-yl]oxy}valeric acid (CHE), were attached to the solid support and were used for syntheses of peptides having a C-terminal amide by the fluorenylmethoxycarbonyl strategy. The cleavability of CHA and CHE was determined and compared with the that commercially available amide handles. CHA and CHE handles can be rapidly cleaved from the polymer support without significant side reactions using lower acid concentrations than those required for conventional handles. As CHA can be easily synthesized in large amounts, it is suitable for peptide amide preparation for pharmaceuticals. As CHE can be cleaved at very low concentrations of acid, it is especially suitable for preparing side chain-protected peptide amides: Several brain-gut peptides having a C-terminal amide were synthesized in high yield and high purity with these novel handles.

  设计，合成和生物评估取代的黄酮和金黄色素作为潜在的抗流感药物。

  摘要：

  我们设计了一系列取代的黄酮和金黄色素作为非竞争性H1N1神经氨酸酶（NA）抑制剂和抗流感药。分子对接研究表明，设计的黄酮和金酮占据了H1N1-NA的150个腔和430个腔。然后，我们合成了这些化合物并评估了它们的细胞毒性，H1N1病毒产量的降低，H1N1-NA的抑制作用以及抑制动力学。病毒减量试验和H1N1-NA抑制试验表明，化合物1f（4-甲氧基黄酮）的最低EC50最低为9.36 nM，IC50最低为8.74μM。此外，动力学研究表明化合物1f和2f具有非竞争性抑制机制。

  electron-withdrawing or-donating substituents on different parts of the molecule, as well as those produced by the incorporation of an additional fused ring, were analyzed. Several compounds showed significant antimalarial activity in vitro with IC50 values as low as 60 nM and a certain efficacy in vivo by reducing parasitemia in Plasmodium berghei mouse models.

  The present invention is directed to novel tricyclic antidepressant drug derivatives synthesized for covalent attachment to proteins or polypeptide antigens for use in the preparation of antibodies or receptors to tricyclic antidepressant drugs and tricyclic antidepressant metabolites. The new derivatives are characterized by a saturated double bond on the amitriptyline portion of the molecule and are represented by the structure where R1 is a saturated or unsaturated, substituted or unsubstituted, straight or branched chain of 0-10 carbon or heteroatoms, X is a linker group consisting of 0-2 substituted or unsubstituted aromatic rings, and Y is an activated ester or NH-Z, where Z is a poly(amino acid). The novel tricyclic antidepressant activated hapten derivatives are useful for preparing tracers and conjugates for tricyclic antidepressant immunoassays, including an enzyme immunoassay and a microparticle capture inhibition assay using an antibody produced from the novel immunogen with a conjugate derivatized either at the N-1 position of imipramine or at the C-2 position of dihydroamitriptyline.
