Huntington’s disease (HD) is a rare single-gene neurodegenerative disease, which can only be treated symptomatically. Currently, there are no approved drugs for HD on the market. Studies have found that MAPK11 can serve as a potential therapeutic target f

Serinol nucleic acid (SNA) is a promising candidate for nucleic acid-based molecular probes and drugs due to its high affinity for RNA. Our previous work revealed that incorporation of 2,6-diaminpurine (D), which can form three hydrogen bonds with uracil, into SNA increases the melting temperature of SNA-RNA duplexes. However, D incorporation into short self-complementary regions of SNA promoted self-dimerization and hindered hybridization with RNA. Here we synthesized a SNA monomer of 2-thiouracil (sU), which was expected to inhibit base pairing with D by steric hindrance between sulfur and the amino group. To prepare the SNA containing D and sU in high yield, we customized the protecting groups on D and sU monomers that can be readily deprotected under acidic conditions. Incorporation of D and sU into SNA facilitated stable duplex formation with target RNA by suppressing the self-hybridization of SNA and increasing the stability of the heteroduplex of SNA and its complementary RNA. Our results have important implications for the development of SNA-based probes and nucleic acid drugs.

Disclosed are compounds that can modulate DDAH and the amount of asymmetric dimethylarginine (ADMA) in a subject. Also provided are pharmaceutical compositions comprising these compounds, as well as methods of using these compositions to treat and/or prevent diseases associated with elevated or low levels of DDAH and ADMA.

Here we report the synthesis of new PNA monomers for pseudocomplementary PNA (pcPNA) that are fully compatible with standard Fmoc chemistry. The thiocarbonyl group of the 2-thiouracil (sU) monomer was protected with the 4-methoxy-2-methybenzyl group (MMPM), while the exocyclic amino groups of diaminopurine (D) were protected with Boc groups. The newly synthesized monomers were incorporated into a 10-mer PNA oligomer using standard Fmoc chemistry for solid-phase synthesis. Oligomerization proceeded smoothly and the HPLC and MALDI-TOF MS analyses indicated that there was no remaining MMPM on the sU nucleobase. The new PNA monomers reported here would facilitate a wide range of applications, such as antigene PNAs and DNA nanotechnologies.

This report describes the syntheses and structure-activity relationships of 8-(4-methoxyphenyl)pyrazolo-[1,5-a]-1,3,5-triazine corticotropin releasing factor receptor-1 (CRF1) receptor antagonists. CRF1 receptor antagonists may be potential anxiolytic or antidepressant drugs. This research culminated in the discovery of analogue 12-3, which is a potent, selective CRF1 antagonist (hCRF1 IC50 ) 4.7 ± 2.0 nM) with weak affinity for the CRF-binding protein and biogenic amine receptors. This compound also has a good pharmacokinetic profile in dogs. Analogue 12-3 is orally effective in two rat models of anxiety: the defensive withdrawal (situational anxiety) model and the elevated plus maze test. Analogue 12-3 has been advanced to clinical trials.
1-(dibromomethyl)-4-methoxy-2-methylbenzene

, p. 317 - 318 (2007/10/03)
The title compound, C9H10Br2O, is a major product of the radical bromination of 4-methoxy-1,2-dimethylbenzene. Each Br atom is involved in a close contact with the O atom of a neighbouring molecule, forming a geometry that is suggestive of weak intermolecular O→Br charge-transfer interactions.
Some evidence in favour of an electron transfer mechanism in the TiO2 photosensitized oxidation of benzyl derivatives in aqueous media
Ranchella, Michele,Rol, Cesare,Sebastiani, Giovanni V.
, p. 311 - 315 (2007/10/03)
The structure and/or distribution of products from the TiO2-sensitized photooxidation of some benzyl derivatives in aerated and/or deaerated aqueous media and in the presence of Ag2SO4 are reported. The results suggest that the single electron transfer process from the substrate to the photogenerated hole, previously proposed in CH3CN, should also be operative on gradually going from aqueous CH3CN to pure water.
