Organogelation behavior, thermal and mechanical properties of polymer network formed by the Diels-Alder reaction of furan- and maleimide-terminated four-arm star-shaped epsilon-caprolactone oligomers

Furan- and maleimide-terminated 4-arm star-shaped epsilon-caprolactone oligomers (F4CLO and M4CLO) were synthesized by the reactions of hydroxy-terminated 4-arm star-shaped epsilon-caprolactone oligomers (H4CLO) having the degree of polymerization per one oligocaprolactone chain, n = 5 or 10 with furfuryl isocyanate and 4-(maleimidophenyl)isocyanate, respectively. Solutions of F4CLO/M4CLO or F4CLO/4,4?-bismaleimidediphenylmethane (BMI) in some organic solvents changed to gels by the Diels-Alder (DA) reaction at 50 C or room temperature, which came back to solutions by the retro-DA (rDA) reaction at 80 C. The thermo-reversible sol-gel process due to the DA and rDA reactions was monitored by 1H NMR and GPC analyses. DSC and XRD analyses of polymer network formed by the DA reaction revealed that the network composed of the oligocaprolactone chain of n = 10 is semicrystalline, while that of n = 5 is amorphous. The former polymer network showed higher tensile strength and modulus than the latter.

Functionalization of NaGdF4 nanoparticles with a dibromomaleimide-terminated polymer for MR/optical imaging of thrombosis

Herein, we report the development of a thrombosis-targeted molecular imaging probe with magnetic resonance (MR) and optical dual-modality capacity using dibromomaleimide (DBM)-bearing polymer-grafted NaGdF4 nanoparticles. The random copolymer of bisphosphonic ester (BPE)-P(OEGA-co-DBM) was first synthesized through reversible addition-fragmentation chain transfer (RAFT) copolymerization of oligo(ethylene glycol)methyl ether acrylate (OEGA) and DBM-based monomers using a BPE-terminated RAFT agent. The resulting polymers were subjected to deprotection with the formation of bisphosphonic acid (BPA) terminals, allowing for the attachment of the as-synthesized BPA-P(OEGA-co-DBM) chains onto the surface of paramagnetic NaGdF4 nanoparticles through the ligand exchange reaction. Azide moieties could be readily incorporated into the hybrid nanoparticles by the coupling reaction between the highly reactive DBM moieties and amine derivatives. Intriguingly, the coupling reaction was characterized by a unique fluorescence turn-on even in aqueous media, which subsequently enabled the fluorescence imaging applications of the resulting hybrid nanoparticle. Furthermore, a single-chain antibody (scFv), which is specifically used for the active conformation of the GPIIb/IIIa integrin, was successfully attached onto the nanoparticles by a strain-promoted copper-free “click” reaction, allowing the targeting of activated platelets in acute thrombosis. The hybrid nanoparticles prepared through this new surface functionalization protocol possessed not only high colloidal stability under physiological conditions but also potential MR/optical imaging capacity. The thrombosis targeting capacity of the hybrid nanoparticle-based probe was then demonstrated by exploiting DBM conjugation-induced fluorescence in living cells.

Development of a long acting human growth hormone analog suitable for once a week dosing

Human growth hormone was conjugated to a carrier aldolase antibody, using a novel linker by connecting a disulphide bond in growth hormone to a lysine-94 amine located on the Fab arm of the antibody. The resulting CovX body showed reduced affinity towards human growth hormone receptor, reduced cell-based activity, but improved pharmacodynamic properties. We have demonstrated that this CovX-body, given once a week, showed comparable activity as growth hormone given daily in an in vivo hypophysectomized rat model.

Fluorescent Labeling of Protein Using Blue-Emitting 8-Amino-BODIPY Derivatives

8-Amino-BODIPY (boron-dipyrromethane) dyes show bright blue fluorescence. Disclosed here are synthesis and characterization of the photophysical properties of a series of functionalized 8-Amino-BODIPY (BP1?4) for protein labeling. The compact structure and solvent-insensitive absorption property of the dye are desirable features for protein labeling. For the model protein, bovine serum albumin (BSA), the labeling proceeds under mild condition via amide bond formation or thiol-ene conjugation with maintaining the bright blue fluorescence. The chromatography and mass spectroscopy analysis clearly support the labeling of the BODIPY dye on the BSA. The protein labeling with blue-emitting BODIPY would be applicable for studying protein dynamics and fluorescence resonance energy transfer (FRET) with intrinsic biomolecules.

Simultaneous determination of fifteen constituents of Jitai tablet using ultra high-performance liquid chromatography coupled with triple quadrupole electrospray tandem mass spectrometry

An ultra-high-performance liquid chromatography-electrospray ionization tandem mass spectrometry (UHPLC-ESI-MS/MS) method was developed for simultaneous determination of fifteen constituents in Jitai tablet (JTT), a complex Traditional Chinese Medicine prescription (TCMP) used in treating opiate addiction. Benefitting from a small particle size (1.8 mum) C18 column, accelerated analysis with satisfactory resolution, sensitivity and selectivity were achieved in a single run within 7 min with linear gradient elution of acetonitrile-0.1% (v/v) formic acid in water. The analytical signal was obtained by multiple reaction monitoring transitions via electrospray ionization source operating in both positive and negative ionization mode. The approach was validated for linearity, sensitivity, precision, repeatability, stability and recovery. All analytes showed good linearity over a wide concentration range (r > 0.99). The method limits ranged from 0.03 ng/mL to 19.35 ng/mL which are sensitive enough for quality control studies. The developed method was successfully applied to the simultaneous determination of fifteen constituents in JTT. In conclusion, our experimental results demonstrate that UHPLC-ESIMS/MS is a useful approach for the overall quality assessment of complex TCMPs.
