A new Ni(dmit)(2)-based organic magnetic charge-transfer salt, (m-PO-CONH-N-methylpyridinium) [Ni(dmit)(2)]center dot CH3CN

A new Ni(dmit)(2)-based organic magnetic charge-transfer (CT) salt, (m-PO-CONH-N-methylpyridinium)[Ni(dmit)(2)]center dot CH3CN, where PO = 2,2,5,5-Tetramethyl-3-pyrrolin-1-oxyl free radical and dmit = 2-Thioxo-1,3-dithiole- 4,5-dithiolate, was obtained, the crystal structure and magnetic properties of which are reported. Magnetic susceptibility of the CT salt obeys a combination of 1D ferromagnetic (1DF) Heisenberg (J(1DF) = +0.26 K) and Singlet-Triplet (ST) models (J(ST) = -51.2 K) with mean field (MF) approximation (J(MF) = -6.7 K), suggesting that spins on the PO radicals form 1D ferromagnetic chains and spins on the Ni (dmit)(2) monoanions form spin dimers at low temperature, the latter of which was also confirmed by band calculations.

Targeted cytotoxic somatostatin analogue AN-238 inhibits somatostatin receptor-positive experimental colon cancers independently of their p53 status

The resistance of advanced colorectal cancers to therapy is often related to mutations in the p53 tumor suppressor gene. Because somatostatin (SRIF) receptors (ssts) are present in colorectal carcinomas, the treatment with targeted cytotoxic SRIF analogue AN-238, consisting of 2-pyrrolin-odoxorubicin (AN-201) linked to octapeptide SRIF carrier RC-121, may overcome this resistance by producing a higher concentration of the cytotoxic agent in the tumors. Four colon cancer cell lines, HCT-116 and LoVo expressing wild-type p53, and HCT-15 and HT-29 with mutated p53, were investigated. HCT-116, HCT-15, and HT-29, but not LoVo possess functional ssts. We analyzed changes in p53, p21, and proliferating cell nuclear antigen (PCNA) concentrations in these cells in vitro by immunoblotting after exposure to AN-238, its radical AN-201, or doxorubicin (DOX). Equitoxic doses of AN-238, AN-201, or DOX affected p53, p21, and PCNA differently. Analysis of the p21:p53 ratios revealed that DOX increased p53 levels, but most of p53 was mutated and inactive, whereas AN-238 produced smaller changes in p53 concentrations but enhanced its activity. In HCT-15 cells, PCNA:p21 ratios, which are indicators of proliferation and repair processes, remained unchanged after exposure to AN-238 but were increased by DOX. In vivo studies in nude mice demonstrated that AN-238, AN-201, and DOX were equally effective on HCT-1 16 tumors that express wild-type p53. However, AN-238 also inhibited the growth of HCT-15 and HT-29 cancers that express mutant p53, whereas AN-201 and DOX showed no effect. None of the compounds could suppress the proliferation of LoVo tumors that lack functional ssts. In conclusion, cytotoxic SRIF analogue AN-238 inhibits the growth of experimental colon cancers that express ssts, regardless of their p53 status.

Synthesis of functionalized 3-, 5-, 6-and 8-aminoquinolines via intermediate (3-pyrrolin-1-yl)- and (2-oxopyrrolidin-1-yl)quinolines and evaluation of their antiplasmodial and antifungal activity

(3-Pyrrolin-1-yl)- and (2-oxopyrrolidin-1-yl)quinolines were prepared via cyclization of diallylaminoquinolines and 4-chloro-N-quinolinylbutanamides, respectively, as novel synthetic intermediates en route to N-functionalized 3-, 5-, 6- and 8-aminoquinolines with potential biological activity. (3-Pyrrolin-1-yl)quinolines were subjected to bromination reactions, and the reactivity of (2-oxopyrrolidin-1-yl)quinolines toward lithium aluminum hydride and methyllithium was assessed, providing an entry into a broad range of novel functionalized (pyrrolidin-1-yl)- and (hydroxyalkylamino) quinolines. Antiplasmodial evaluation of these novel quinolines and their functionalized derivatives revealed moderate micromolar potency against a chloroquine-sensitive strain of the malaria parasite Plasmodium falciparum, and the two most potent compounds also showed micromolar activity against a chloroquine-resistant strain of P. falciparum. Antifungal assessment of (hydroxyalkylamino)quinolines revealed three compounds with promising MIC values against Rhodotorula bogoriensis and one compound with potent activity against Aspergillus flavus.

Spin labeling of oligonucleotides with the nitroxide TPA and use of PELDOR, a pulse EPR method, to measure intramolecular distances

In this protocol, we describe the facile synthesis of the nitroxide spin-label 2,2,5,5-tetramethyl-pyrrolin-1-oxyl-3-acetylene (TPA) and then its coupling to DNA/RNA through Sonogashira cross-coupling during automated solid-phase synthesis. Subsequently, we explain how to perform distance measurements between two such spin-labels on RNA/DNA using the pulsed electron paramagnetic resonance method pulsed electron double resonance (PELDOR). This combination of methods can be used to study global structure elements of oligonucleotides in frozen solution at RNA/DNA amounts of similar to 10 nmol. We especially focus on the Sonogashira cross-coupling step, the advantages of the ACE chemistry together with the appropriate parameters for the RNA synthesizer and on the PELDOR data analysis. This procedure is applicable to RNA/DNA strands of up to similar to 80 bases in length and PELDOR yields reliably spin-spin distances up to similar to 6.5 nm. The synthesis of TPA takes similar to 5 days and spin labeling together with purification similar to 4 days. The PELDOR measurements usually take similar to 16 h and data analysis from an hour up to several days depending on the extent of analysis.

Base-catalyzed reaction between isatins and N-Boc-3-pyrrolin-2-one

The base-catalyzed reaction between isatins and N-Boc-3-pyrrolin-2-one yields Morita-Baylis-Hillman (MBH) adducts instead of the expected aldol products in good to high yields (up to 97%). Various organic and inorganic bases are efficient catalysts for this reaction. Our study excluded the Morita-Baylis-Hillman mechanism for the formation of the MBH-type products. The MBH products are most likely formed as a result of the subsequent isomerization of the original aldol products between isatins and N-Boc-3-pyrrolin-2-one. (C) 2013 Elsevier Ltd.

Synthesis of new bicyclic analogues of glutamic acid

Regioisomeric 3-hydroxyisoxazolinyl prolines [HIP-A (+/-)-6 and HIP-B (+/-)-7], which represent a restricted conformation of NMDA, AMPA, and kainic acid, potent and selective agonists at ionotropic glutamate receptors, have been prepared through two different strategies. In the first approach bromonitrile oxide was added to N-BOC-Delta(3)-pyrroline or N-BOC-Delta(3)-pyrrolin-2-one and the carboxylic group was subsequently appended. The alternative strategy is based on the cycloaddition of the same 1,3-dipole to NBOC-3,3-didehydroproline methyl ester, (C) 1999 Elsevier Science Ltd. All rights reserved.

A novel biomimetic route to the 3-acyl-5-hydroxy-3-pyrrolin-2-one and 3-acyl-3,4-epoxy-5-hydroxypyrrolidin-2-one ring systems

Modified Moffat oxidation of alcohols 17, 22, and 25 afforded aldehydes that underwent intramolecular aldol reactions on treatment with a NaOH solution to yield 4-pyrrolin-2-ones 16, 23, and 26. Oxidation with DMDO at -40 degreesC provided 3-acyl-5-hydroxy-3-pyrrolin-2-ones 18, 24, and 27 with the ring system of oteromycin (3), UCS1025A (5), and related natural products. Further oxidation of 18 yielded 3-acyl-3,4-epoxy-5-hydroxy-pyrrolidin-2-one 19 with the ring system of fusarin C (1) and epolactaene (2). Dehydration of 18 afforded 20 with the talaroconvolutin A (4) ring system.
