Purinenucleoside derivative modified in 8-position and medical use thereof

The present invention provides an 8-modified purinenucleoside derivative which is useful for diseases associated with an abnormality of plasma uric acid level. An 8-modified purinenucleoside derivative represented by the following formula (I), a prodrug thereof or a pharmaceutically acceptable salt thereof, or a hydrate or solvate thereof, is useful for the prevention or treatment of gout, hyperuricemia, urinary lithiasis, hyperuricemic nephropathy or the like. In the formula, n is 1 or 2; RA is a hydrogen atom or a hydroxyl group; R1 is a hydrogen atom, a hydroxyl group, a thiol group, an amino group or a chlorine atom; ring J represents an optionally substituted 2-naphthyl group, or a group represented by the following general formula (II) wherein Y represents a single bond or a connecting group; ring Z represents an optionally substituted aryl group or heteroaryl group or the like; and R2 to R4, P1 and Q represents a halogen atom, a cyano group or the like.

NOVEL ANTIMALARIA AGENT CONTAINING HETEROCYCLIC COMPOUND

Disclosed is an antimalarial agent containing a compound represented by the formula: [wherein A1 represents a 3-pyridyl group that may have a substituent, a 6-quinolyl group that may have a substituent, or the like; X1 represents a group represented by the formula -C(=O)-NH- or the like; E represents a furyl group, a thienyl group or a phenyl group; with the proviso that A1 may have one to three substituents, and E has one of two substituents] or a salt thereof or hydrates thereof.

Design, synthesis, and conformational dynamics of a gated molecular basket

We have developed a synthesis and examined the conformational behavior and recognition properties of dynamic molecular containers 1-3. As follows from the 1H NMR dilution, diffusion NMR, and vapor pressure osmometry measurements, compound 1 has a low affinity for intermolecular aggregation and is mostly present in monomeric form in dilute chloroform solutions. Inspecting the O-H chemical shift resonances of 1, 3, and model compound 4 as a function of temperature afforded the Δδ/ΔT coefficients of 17.0, 17.3, and 4.7 ppb K-1, respectively. In combination with the results from variable temperature 1H NMR and IR measurements, the existence of conformers of 1 and 3 in equilibrium, each having a different extent of hydrogen bonding, was confirmed. Molecular mechanics calculations suggested 1 a as the most favorable conformation, with three additional conformers, 1b, 1C, and 1d, populating local energy minima. Further optimization of each of the four conformers using semiempirical PM3 and ab initio (HF/6-31G*) methods allowed a determination of their relative free energies and the corresponding Boltzmann population distributions which were heavily weighted toward 1a. A computed composite IR spectrum of a fraction-weighted mixture of the conformers of 1 reproduced the experimentally observed IR spectrum in its structural features, leading to a conclusion that conformer 1a indeed dominates the equilibrium. The egg-shaped cavity of 1 (136.6 A3) is complementary in size, shape, and electrostatic potential to chloroform (74.9 A3). A single-crystal X-ray study of 2 revealed a disordered chloroform molecule positioned inside the cavitand along its C3, axis.
