In vivo cultivation of tumor cells in hollow fibers

Advancement of potential anti-cancer agents from ‘discovery’ in an in vitro screen to pre-clinical development requires a demonstration of in vivo efficacy in one or more animal models of neoplastic disease. Most such models require considerable materials in terms of laboratory animals and test compound as well as substantial amounts of time (and cost) to determine whether a given experimental agent or series of agents have even minimal anti-tumor activity. The present study was initiated to assess the feasibility of employing an alternate methodology for preliminary in vivo evaluations of therapeutic efficacy. Results of experimentation to date demonstrate that a hollow fiber encapsulation/implantation methodology provides quantitative indices of drug efficacy with minimum expenditure of time and materials. Following further pharmacologic calibrations, the hollow fiber technique is anticipated (a) to identify compounds having moderate to prominent anti-cancer activity and (b) to facilitate the identification of sensitive tumor cell line ‘targets’ and optimal or near-optimal treatment regimens for subsequent testing using standard in vivo solid tumor models. The potential suitability of this methodology is demonstrated with several standard anti-neoplastic agents.

Chemical-induced inhibition of blue light-mediated seedling development caused by disruption of upstream signal transduction involving cryptochromes in Arabidopsis thaliana

Plants have a remarkable ability to perceive and respond to various wavelengths of light and initiate regulation of different cascades of light signaling and molecular components. While the perception of red light and the mechanisms of its signaling involving phytochromes are largely known, knowledge of the mechanisms of blue light signaling is still limited. Chemical genetics involves the use of diverse small active or synthetic molecules to evaluate biological processes. By combining chemicals and analyzing the effects they have on plant morphology, we identified a chemical, 3-bromo-7-nitroindazole (3B7N), that promotes hypocotyl elongation of wild-type Arabidopsis only under continuous blue light. Further evaluation with loss-of-function mutants confirmed that 3B7N inhibits photomorphogenesis through cryptochrome-mediated light signaling. Microarray analysis demonstrated that the effect of 3B7N treatment on gene expression in cry1cry2 is considerably smaller than that in the wild type, indicating that 3B7N specifically interrupts cryptochrome function in the control of seedling development in a light-dependent manner. We demonstrated that 3B7N directly binds to CRY1 protein using an in vitro binding assay. These results suggest that 3B7N is a novel chemical that directly inhibits plant cryptochrome function by physical binding. The application of 3B7N can be used on other plants to study further the blue light mechanism and the genetic control of cryptochromes in the growth and development of plant species.

Site-Specific 89Zr- And 111In-Radiolabeling and in Vivo Evaluation of Glycan-free Antibodies by Azide-Alkyne Cycloaddition with a Non-natural Amino Acid

Antibody-drug conjugates (ADCs) are a class of targeted therapeutics consisting of a monoclonal antibody coupled to a cytotoxic payload. Various bioconjugation methods for producing site-specific ADCs have been reported recently, in efforts to improve immunoreactivity and pharmacokinetics and minimize batch variance – potential issues associated with first-generation ADCs prepared via stochastic peptide coupling of lysines or reduced cysteines. Recently, cell-free protein synthesis of antibodies incorporating para-azidomethyl phenylalanine (pAMF) at specific locations within the protein sequence has emerged as a means to generate antibody-drug conjugates with strictly defined drug-antibody-ratio, leading to ADCs with markedly improved stability, activity, and specificity. The incorporation of pAMF enables the conjugation of payloads functionalized for strain-promoted azide-alkyne cycloaddition. Here, we introduce two dibenzylcyclooctyne-functionalized bifunctional chelators that enable the incorporation of radioisotopes for positron emission tomography with 89Zr (t1/2 = 78.4 h, beta+ = 395 keV (22%), gamma= 897 keV) or single photon emission computed tomography with 111In (t1/2 = 67.3 h, gamma= 171 keV (91%), 245 keV (94%)) under physiologically compatible conditions. We show that the corresponding radiolabeled conjugates with site-specifically functionalized antibodies targeting HER2 are amenable to targeted molecular imaging of HER2+ expressing tumor xenografts in mice and exhibit a favorable biodistribution profile in comparison with conventional, glycosylated antibody conjugates generated by stochastic bioconjugation.

Isoform specific inhibition for treatment of pain and reduction of anesthetic threshold

Several lines of evidence have shown a role for the nitric oxide (NO)/cyclic guanosine monophosphate (cGMP) signaling pathway in the development of spinal hyperalgesia. However, the roles of effectors for cGMP are not fully understood in the processing of pain in the spinal cord. cGMP-dependent protein kinase (PKG) Ialpha but not PKGIbeta was localized in the neuronal bodies and processes, and was distributed primarily in the superficial laminae of the spinal cord. Intrathecal administration of an inhibitor of PKGIalpha, Rp-8-[(4-Chlorophenyl)thio]-cGMPS triethylamine, produces significant antinociception. Moreover, PKGIalpha protein expression was dramatically increased in the lumbar spinal cord after noxious stimulation. This upregulation of PKGIalpha expression was completely blocked not only by a neuronal NO synthase inhibitor, and a soluble guanylate cyclase inhibitor, but also by an N-methyl-D-aspartate (NMDA) receptor antagonist, MK-801. Noxious stimulation not only initially activates but also later upregulates PKGIalpha expression in the superficial laminae via an NMDA-NO-cGMP signaling pathway, suggesting that PKGIalpha plays an important role in the central mechanism of inflammatory hyperalgesia in the spinal cord.

Toward development of targeted nonsteroidal antiandrogen-1,4,7,10- tetraazacyclododecane-1,4,7,10-tetraacetic acid-gadolinium complex for prostate cancer diagnostics

Androgen receptors are present in most advanced prostate cancer specimens, having a critical role in development of this type of cancer. For correct prognosis of patient conditions and treatment monitoring, noninvasive imaging techniques have great advantages over surgical procedures. We developed synthetic methodologies for preparation of novel androgen receptor-targeting agents in an attempt to build a versatile platform for prostate cancer imaging and treatment. The structure of these compounds comprises of a lanthanoid metal ion, gadolinium-1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (Gd-DOTA)-based binding fragment and, connected to it by a flexible linker, bicalutamide-derived nonsteroidal antiandrogen moiety. A representative gadolinium complex 15 was evaluated as a magnetic resonance imaging (MRI) agent in C57/bl6 male mouse bearing orthotopic TRAMP C2 prostate tumor.

Synthesis and Molecular Structures of Hydrotris(dimethylpyrazolyl)borate Complexes of the Lanthanides

The reaction of lanthanide triflates with 2 equiv of potassium hydrotris(dimethylpyrazolyl)borate (TpMe2) gives good yields of complexes of composition Ln(TpMe2)2OTf. For La (2), Ce (3), Pr (4), and Nd (5) the complexes are seven-coordinate in the solid state with the triflate group coordinated to the metal in unidentate fashion. Complex 5 crystallizes in the monoclinic space group P21/c with a = 17.629(3) A, b = 12.740(2) A, c = 18.163(3) A, beta = 107.35(1), V = 3893(1) A3, Z = 4, and Rw = 0.0458. For the complexes of Y (1), Sm (6), Eu (7), Gd (8), Dy (9), Ho (10), and Yb (11), the smaller size of the metal ion leads to ejection of the triflate from the coordination sphere and the complexes are ionic in the solid state with a six-coordinate metal center. Complex 11 crystallizes in the monoclinic space group C2/m with a = 16.593(7) A, b = 13.671(5) A, c = 8.746(2) A, beta = 91.66(3), V = 1983(1) A3, Z = 2, and Rw = 0.0416. In solution, however, complex 6 adopts a seven-coordinate molecular structure with the triflate ion within the first coordination sphere.

Double Diastereoselective Approach to Chiral syn- and anti-1,3-Diol Analogues through Consecutive Catalytic Asymmetric Borylations

Homoallylic boronate carboxylate esters derived from unsaturated aldehydes via an imination, beta-borylation, imine hydrolysis, and Wittig trapping sequence, were subjected to a second boryl addition to give 1,3-diborylated carboxylate esters. Control of the absolute and relative stereochemistry of the two new 1,3-stereogenic centers was achieved through: (1) direct chiral catalyst controlled asymmetric borylation of the first stereocenter on the unsaturated imine with high e.e.; and (2) a double diastereoselectively controlled borylation of an unsaturated ester employing a chiral catalyst to largely overcome directing effects from the first chiral boryl center to give poor (mismatched) to good (matched) diastereocontrol. Subsequently, the two C-B functions were transformed into C-O systems to allow unambiguous stereochemical assignment of the two borylation reactions involving oxidation and acetal formation.
