Tuning the Hydrolytic Stability of Next Generation Maleimide Cross-Linkers Enables Access to Albumin-Antibody Fragment Conjugates and tri-scFvs

We describe investigations to expand the scope of next generation maleimide cross-linkers for the construction of homogeneous protein-protein conjugates. Diiodomaleimides are shown to offer the ideal properties of rapid bioconjugation with reduced hydrolysis, allowing the cross-linking of even sterically hindered systems. The optimized linkers are exploited to link human serum albumin to antibody fragments (Fab or scFv) as a prospective half-life extension platform, with retention of antigen binding and robust serum stability. Finally, a triprotein conjugate is formed, by linking scFv antibody fragments targeting carcinoembryonic antigen. This tri-scFv is shown to infer a combination of greater antigen avidity and increased in vivo half-life, representing a promising platform for antibody therapeutic development.

ALKALOIDS FROM Corydalis nobilis (L.) Pers. AND C. intermedia (L.) MERAT

Rhizomes of Corydalis nobilis (L.) Pers. (3percent of alkaloids) contain (+)-tetrahydropalmitine, (+)-bicuculline and (+)-corytuberine as the main constituents of the tertiary alkaloid fraction.Protopine, (+)-corypalmine and (+)-stylopine, which also belong to the dominant alkaloids, were isolated in lesser amounts.As minor alkaloids were isolated (+/-)-tetrahydropalmatine, (+)-corydaline, allocryptopine, cryptopine, (-)-scoulerine, (+)-adlumidine, (+)-sinactine, (+/-)-corlumine, isoboldine, (+)-corybulbine, (+/-)-stylopine and (-)-isocorypalmine.The fraction of quaternary protoberberine alkaloids afforded coptisine, dehydrocorydaline, palmatine, corysamine, jatrorrhyzine and cis-N-methylstylopinium hydroxide.Aobamidine (Z-adlumidiceine enol lactone), isolated as the principal alkaloid of aerial parts (0.3 percent of alkaloids), is obviously an artifact arising from bicuculline N-metho salt during the isolation process.Further dominant alkaloids of the tertiary fraction were adlumidine, bicuculline, protopine, (+/-)-tetrahydropalmatine and (+/-)-corlumine; as minor alkaloids were isolated corytuberine, scoulerine, corypalmine, cryptopine, isocorypalmine, corybulbine, (+)-corydalidzine, and unidentified alkaloids CN 1 (C23H25NO5, m.p.211 deg C) and CN 2 (m.p.261 deg C).Quternary protoberberine fraction afforded coptisine and palmatine.Nineteen of the mentioned alkaloids were isolated froom this species for the first time.Tubers of C.intermedia (L.) Merat (0.7 percent of alkaloids) afforded protopine, tetrahydropalmatine and corydaline as the main alkaloids and allocryptopine, canadine, stylopine, palmatine, dehydrocorydaline, berberine, coptisine as minor alkaloids, together with traces of bicuculline and magnoflorine.Dominant alkaloids of the aerial part (0.73 percent of alkaloids) were bicuculline, bulbocapnine, protopine, stilopine and an unidentified phenolic base, m.p. 258 deg C.Isoboldine, scoulerine, allocryptopine, corydaline, canadine, coptisine, palmatine and berberine were identified as the minor alkaloids.

Synthesis of indoles via 6pi-electrocyclic ring closures of trienecarbamates

A new method for the preparation of indoles from readily available alpha-haloenones and alpha-(trialkylstannyl)enecarbamates is described. Following a Stille coupling, trienecarbamate 2 is electronically activated to undergo a facile 6pi-electrocyclic ring closure and subsequent oxidation to afford protected aniline 4. Upon deprotection and reductive amination, acid 5 underwent clean cyclization to N-acetylindole 6 (Ac2O, NEt3, 130 C). This method has been used to construct a variety of substituted indoles that are not easily prepared by conventional indole annelation methods. Copyright

Syntheses of Reactive Fluorescent Stains Derived from 5(2)-Aryl-2(5)-(4-pyridyl)oxazoles and Bifunctionally Reactive Linkers

Several bifunctionally reactive linkers containing halide or sulfonate ester groups were prepared.The linkers were used to quaternize 5-(4-methoxyphenyl)-2-(4-pyridyl)oxazole and 2-(6-chromanyl)-5-(4-pyridyl)oxazole to produce fluorescent stains that contained a reactive group such as an isothiocyanate, an N-hydroxysuccinimidyl ester, a maleimide, or an oxirane.The stains were derivatized with either 1-propyl-amine, 1-propanethiol, or piperidine, as appropriate, to help in characteriazation.The stains may serve as more photostable alternatives to fluoresceins or coumarins.

Structural characterization and identification of major constituents in jitai tablets by high-performance liquid chromatography/diode-array detection coupled with electrospray ionization tandem mass spectrometry

In the present study a universally applicable HPLC-DAD/ESI-MS/MS method was developed for carrying out the comprehensive characterization of Jitai tablets (JTT). Based on the ESI-MSn fragmentation patterns of the reference standards, a total of 101 components were identified or tentatively characterized by comparing their retention times, UV and MS spectra with those of reference standards or through the matching of empirical information with those of published components in the in-house library. The characteristic fragmentation pattern of alkaloids, phenolic acids, tanshinones, flavonoid glycosides, cyanogenic glycosides, ginsenosides, 2-(2-phenylethyl) chromones, phthalides and gingerol-related compounds were tentatively elucidated using structurally-relevant product ions. It was observed that neutral losses of C9H10O3 and C9H8O 2 were the characteristic product ions of scopola alkaloids. Neutral fragment mandelonitrile was the characteristic ion of cyanogenic glycosides. To our knowledge, tropylium ion and C4H2O unit were the characteristic ions of 2-(2-phenylethyl) chromone, which resulted from the Retro-Diels-Alder (RDA) cleavage of the C ring. The results indicated that the developed analysis method could be employed as a rapid, effective technique for structural characterization of chemical constituents in TCM. This work is expected to provide comprehensive information for the quality evaluation and pharmacokinetic studies of JTT.
