Abstract
Pin1 is a peptidyl prolyl cis-trans isomerase (PPIase) and inhibiting Pin1 is a potential way for discovering anti-tumor agents. With an aim to find potent Pin1 inhibitors with a novel scaffold, a series of thiazole derivatives with an alicyclic heterocycles on the 2-position were designed, synthesized and tested against human Pin1. Compound 9p bearing a 2-oxa-6-azaspiro [3,3] heptane moiety on the thiazole scaffold was identified as the most potent Pin1 inhibitor of this series with an IC50 value of 0.95 μM. The structure-activity relationship (SAR) and molecular modeling study indicated that introducing an alicyclic ring with an H-bond acceptor would be a viable way to improve the binding affinity.

Abstract
Nonstabilized azomethine ylides derived from decarboxylation of oxazolidin-5-ones were used for double 1,3-dipolar cycloadditions in diastereoselective synthesis of pyrrolidine-containing tetracyclic compounds. This is the first example of one-pot and five-component reactions involving two nonstabilized azomethine ylides. Only CO2 and water were generated as byproducts.

Abstract
We have carried out the optimization of substituents at the C-3 or the C-5 position on the pyrrolidine ring of VLA-4 antagonist 3 with 2-(phenylamino)-7-fluorobenzoxazolyl moiety for the purpose of improving in vivo efficacy while maintaining good aqueous solubility. As a result, we successfully increased in vitro activity in the presence of 3% human serum albumin and achieved an exquisite lipophilic and hydrophilic balance of compounds suitable for oral administrative regimen. The modification resulted in the identification of zwitterionic compound 7n with (5S)-[methoxy(methyl)amino]methylpyrrolidine, which significantly alleviated bronchial hyper-responsiveness to acetylcholine chloride at 12.5mg/kg, p.o. in a murine asthma model and showed favorable aqueous solubility (JP1, 89 μg/mL; JP2, 462 μg/mL). Furthermore, this compound showed good oral bioavailability (F=54%) in monkeys.

Abstract
The cis peptide bond is a characteristic feature of turns in protein structures and can play the role of a hinge in protein folding. Such cis conformations are most commonly found at peptide bonds immediately preceding proline residues, as the cis and trans states for such bonds are close in energy. However, isomerization over the high rotational barrier is slow. In this study, we investigate how mechanical force accelerates the cis to trans isomerization of the prolyl-peptide bond in a stretched backbone. We employ hybrid quantum mechanical/molecular mechanical force-clamp molecular dynamics simulations in order to describe the electronic effects involved. Under tension, the bond order of the prolyl-peptide bond decreases from a partially double toward a single bond, involving a reduction in the electronic conjugation around the peptide bond. The conformational change from cis to extended trans takes place within a few femtoseconds through a nonplanar state of the nitrogen of the peptide moiety in the transition state region, whereupon the partial double-bond character and planarity of the peptide bond in the final trans state is restored. Our findings give insight into how prolyl-peptide bonds might act as force-modulated mechanical timers or switches in the refolding of proteins.

Abstract
The important roles of a nuclear receptor peroxisome proliferator-activated receptor gamma (PPARgamma) are widely accepted in various biological processes as well as metabolic diseases. Despite the worldwide quest for pharmaceutical manipulation of PPARgamma activity through the ligand-binding domain, very little information about the activation mechanism of the N-terminal activation function-1 (AF-1) domain. Here, we demonstrate the molecular and structural basis of the phosphorylation-dependent regulation of PPARgamma activity by a peptidyl-prolyl isomerase, Pin1. Pin1 interacts with the phosphorylated AF-1 domain, thereby inhibiting the polyubiquitination of PPARgamma. The interaction and inhibition are dependent upon the WW domain of Pin1 but are independent of peptidyl-prolyl cis/trans-isomerase activity. Gene knockdown experiments revealed that Pin1 inhibits the PPARgamma-dependent gene expression in THP-1 macrophage-like cells. Thus, our results suggest that Pin1 regulates macrophage function through the direct binding to the phosphorylated AF-1 domain of PPARgamma.

Abstract
Fredericamycin (FDM) A ( 1), a pentadecaketide featuring two sets of peri-hydroxy tricyclic aromatic moieties connected through a unique asymmetric carbaspiro center, exhibits potent cytotoxicity and represents a novel anticancer drug lead. We have localized previously the fdm gene cluster to a 33 kb DNA segment of Streptomyces griseus ATCC49344, the involvement of which in the biosynthesis of 1 was confirmed by gene inactivation, complementation, and heterologous expression experiments. We now report the isolation and characterization of FDM E ( 5), a heretofore undetected intermediate for 1 biosynthesis from S. griseus, shedding new insight into the mechanism of carbaspirocycle formation. The structure of 5 was elucidated through the combination of spectroscopic methods and isotope-labeling experiments. The core spiro[4.5]decane scaffold of 5 is characterized by a unique cyclohexa-1,2,4-triketone moiety. Transformation of the spiro[4.5]decane 5 into the spiro[4.4]nonane 1 can be rationalized by a biosynthetic benzilic acid-like rearrangement. This unusual rearrangement can be mimicked in vitro by proceeding under aerobic conditions in the absence of enzyme. FDM E displays cytotoxic activity on par with 1 against a selected set of cancer cells, a finding that further supports the unique molecular topology, resulting from the unprecedented carbaspirocycle as exemplified by 1 and 5, as a novel pharmacophore for this family of anticancer agents.

Abstract
This review describes simple and useful concepts for predicting and tuning the pK(a) values of basic amine centers, a crucial step in the optimization of physical and ADME properties of many lead structures in drug-discovery research. The article starts with a case study of tricyclic thrombin inhibitors featuring a tertiary amine center with pK(a) values that can be tuned over a wide range, from the usual value of around 10 to below 2 by (remote) neighboring functionalities commonly encountered in medicinal chemistry. Next, the changes in pK(a) of acyclic and cyclic amines upon substitution by fluorine, oxygen, nitrogen, and sulfur functionalities, as well as carbonyl and carboxyl derivatives are systematically analyzed, leading to the derivation of simple rules for pK(a) prediction. Electronic and stereoelectronic effects in cyclic amines are discussed, and the emerging computational methods for pK(a) predictions are briefly surveyed. The rules for tuning amine basicities should not only be of interest in drug-discovery research, but also to the development of new crop-protection agents, new amine ligands for organometallic complexes, and in particular, to the growing field of amine-based organocatalysis.
