Synthesis and biological evaluation of coumarin replacements of novobiocin as Hsp90 inhibitors
Since Hsp90 modulates all six hallmarks of cancer simultaneously, it has become an attractive target for the development of cancer chemotherapeutics. In an effort to develop more efficacious compounds for Hsp90 inhibition, novobiocin analogues were prepared by replacing the central coumarin core with naphthalene, quinolinone, and quinoline surrogates. These modifications allowed for modification of the 2-position, which was previously unexplored. Biological evaluation of these compounds suggests a hydrophobic pocket about the 2-position of novobiocin. Anti-proliferative activities of these analogues against multiple cancer cell lines identified 2-alkoxyquinoline derivatives to exhibit improved activity.

Toward biophysical probes for the 5-HT3 receptor: Structure-activity relationship study of granisetron derivatives
This report describes the synthesis and biological characterization of novel granisetron derivatives that are antagonists of the human serotonin (5-HT3A) receptor. Some of these substituted granisetron derivatives showed low nanomolar binding affinity and allowed the identification of positions on the granisetron core that might be used as attachment points for biophysical tags. A BODIPY fluorophore was appended to one such position and specifically bound to 5-HT3A receptors in mammalian cells.

Protective Agent for Retinal Neuronal Cell Comprising Indazole Derivative as Active Ingredient
As a result of intensive studies for the purpose of finding a new medicinal use of an indazole derivative, it was found that an indazole derivative inhibits glutamate-induced retinal neuronal cell death in rat fetal retinal neuronal cells, in other words, the indazole derivative acts directly on the retinal neuronal cells and exhibits an effect of protecting retinal neuronal cells. Accordingly, the indazole derivative is useful for the prevention or treatment of an eye disease associated with retinal neuronal cell damage or retinal damage.

Structure-activity relationship study on a novel series of cyclopentane-containing macrocyclic inhibitors of the hepatitis C virus NS3/4A protease leading to the discovery of TMC435350
SAR analysis performed with a limited set of cyclopentane-containing macrocycles led to the identification of N-[17-[2-(4-isopropylthiazole-2-yl)-7-methoxy-8-methylquinolin-4-yloxy]- 13-methyl-2,14-dioxo-3,13-diazatricyclo [13.3.0.04,6]octadec-7-ene-4-carbonyl](cyclopropyl)sulfonamid e (TMC435350, 32c) as a potent inhibitor of HCV NS3/4A protease (Ki = 0.36 nM) and viral replication (replicon EC50 = 7.8 nM). TMC435350 also displayed low in vitro clearance and high permeability, which were confirmed by in vivo pharmacokinetic studies. TMC435350 is currently being evaluated in the clinics.

Discovery of novel potent and selective dipeptide hepatitis C virus NS3/4A serine protease inhibitors
Starting from the previously reported HCV NS3/4A protease inhibitor BILN 2061 (1), we have used a fast-follower approach to identify a novel series of HCV NS3/4A protease inhibitors in which (i) the P3 amino moiety and its capping group have been truncated, (ii) a sulfonamide is introduced in the P1 cyclopropyl amino acid, (iii) the position 8 of the quinoline is substituted with a methyl or halo group, and (iv) the ring size of the macrocycle has been reduced to 14 atoms. SAR analysis performed with a limited set of compounds led to the identification of N-{17-[8-chloro-2-(4-isopropylthiazol-2-yl)-7-methoxyquinolin-4-yloxy]-2,14-dioxo-3,15-diazatricyclo [13.3.0.0 [Bartenschlager, R.; Lohmann, V.

Structure-activity relationships in the acronycine and benzo[b]acronycine series: Role of the pyran ring
In order to explore the structure-activity relationships in the acronycine series, simplified analogues of cis-1,2-diacetoxy-1,2-dihydroacronycine and cis-1,2-diacetoxy-1,2-dihydrobenzo[b]acronycine (S23906-1, under clinical trials) lacking the fused pyran ring, but possessing an acetoxymethyl leaving group at position 4 were prepared. These new analogues only displayed marginal antiproliferative activity compared to the parent compounds. The presence of the angularly fused dimethylpyran ring appears as an indispensable structural requirement to observe significant cytotoxic activity in this series.

Collisionally induced dissociation in the study of A-ring hydroxylated vitamin D type compounds
Colllslonally Induced dissociation (CID) is often used to determine the structure of ions based on comparison with the CID spectra of known ions. The latter are generated from Judiciously selected compounds taking into account basic principles of Ion chemistry. We report here on the use of this approach toward determination of the site of A-ring hydroxylation of vitamin D. Although not Intrinsically an aromatic compound, vitamin D gives rise in its mass spectrum to an aromatic methytstyryl cation at mlz 118. A-ring hydroxylated metabolites of vitamin D would thus Incorporate the extra OH group on the ion at mlz 118, shifting it to mlz 134. The position of substitution of the extra OH group on a metabolite could then be ascertained by comparing the CID spectrum of its mlz 134 fragment to those of the four possible (hydroxymethyl)styryl cations generated from synthesized authentic compounds. Because of their propensity to polymerize, these cations were generated in situ via the McLafferty rearrangement of the corresponding (hydroxyphenyl)ethanols. For optimum differentiation of Isomeric Ions, preparation of permethylated derivatives of vitamin D was necessary. The validity of the hypothesis was verified using 1,25-dihydroxy-vitamin D3 as a test compound. This method provides a viable approach for the characterization of A-ring hydroxylated metabolites of vitamin D as well as for related aromatic compounds.
