Novel echinocandin antifungals. Part 2: Optimization of the side chain of the natural product FR901379. Discovery of micafungin

Further optimization of the potent antifungal activity of side chain analogs of the natural product FR901379 led to the discovery of compound 8 with an excellent, well-balanced profile. Potent compounds with reduced hemolytic potential were designed based upon a disruption of the linearity of the terphenyl lipophilic side chain. The optimized compound (8, FK463, micafungin) displayed the best balance and was selected as the clinical candidate.

AgNTf2-catalyzed formal [3 + 2] cycloaddition of ynamides with unprotected isoxazol-5-amines: Efficient access to functionalized 5-amino-1H-pyrrole-3-carboxamide derivatives

A formal [3 + 2] cycloaddition between ynamides and unprotected isoxazol-5-amines has been developed in the presence of catalytic AgNTf2 in an open flask. By the protocol, a variety of functionalized 5-amino-1H-pyrrole-3-carboxamide derivatives can be obtained in up to 99% yield. The reaction mechanism might involve the generation of an unusual alpha-imino silver carbene intermediate (or a silver-stabilized carbocation) and subsequent cyclization/isomerization to build the significant pyrrole-3-carboxamide motif. The reaction features the use of an inexpensive catalyst, simple reaction conditions, simple work-up without column chromatographic purification for most of products and high yields.

Reactions of Lithiated Methoxyallene with Oxime Derivatives ? Formation of 1,2-Oxazines and Functionalized Isoxazole Derivatives

In a brief exploratory study we investigated the reactions of lithiated methoxyallene with different oxime derivatives. With E-benzaldehyde oxime a 3,6-dihydro-2H-1,2-oxazine derivative was isolated in low yield, being the result of an overall [3+3] cyclization. The reaction of lithiated methoxyallene with phenylhydroximoyl chloride provided a moderate yield of an isoxazole derivative that incorporated two benzonitrile oxide-derived moieties. In situ generated alpha-nitrosostyrene and lithiated methoxyallene combine to the expected primary 1,4-addition product which could be trapped by O-methylation. On the other hand, the primary adduct cyclized after aqueous work-up to give a vinyl-substituted isoxazole derivative in good yield. Mechanisms for the formation of the products are presented. The discovered new routes to 1,2-oxazine or isoxazole derivatives seem to be restricted to aryl-substituted electrophiles.

A new synthesis method of N-substituted spiro terpene aza-diperoxides

[Figure not available: see fulltext.] An efficient method has been developed for the synthesis of new spiro terpene aza-diperoxides by heterocyclization of bishydroperoxides with N-aryl-N,N-bis(methoxymethyl)amines in the presence of EuCl3/gamma-Al2O3 as a catalyst. The assignment of signals in the NMR spectra of the synthesized compounds was performed taking into account the dynamics of the conformation of the tetraoxazocane ring with two rigid peroxide bonds. Structures of some aza-diperoxides were determined by X-ray structural analysis.

High overtones of C-H stretching vibrations in isoxazole, thiazole, and related methyl and dimethyl derivatives

The high overtone spectra of liquid isoxazole and thiazole, two five-membered heterocyclic molecules with different aromaticity characters, have been investigated in the C-H stretching region by visible absorption spectroscopy. The local-mode model describes satisfactorily the C-H stretching vibrations at the fifth and sixth quanta of excitation, where the localized character is increased. Each overtone band generally displays a number of peaks corresponding to the different types of C-H oscillators. Comparison between the overtone spectra of the parent molecules and those of the methyl derivatives provided sufficient information for a conclusive assignment of the progressions. Deconvolution of the fifth overtone bands gave further evidence regarding the shape and the width of the distinct peaks. Anharmonicity values of the overtone vibrations, C-H bond lengths, and force constants were obtained from the local-mode analysis and discussed in comparison with the results obtained from the normal-mode approximation. A correlation between overtone frequencies and chemical shifts in proton magnetic resonance, generally observed in aromatic compounds, has been found only for thiazole, whose aromaticity is responsible for a significant electron current in the ring.

Anti-Helicobacter pylori agents. 5. 2-(Substituted guanidino)-4-arylthiazoles and aryloxazole analogues

To extend the SAR study of guanidinothiazoles as a structurally novel class of anti-H. pylori agents, a series of 2-(substituted guanidino)-4-arylthiazoles and some 4-aryloxazole analogues were synthesized and evaluated for antimicrobial activity against H. pylori. Some of them were also subjected to H2 antagonist and gastric antisecretory assays. Several arylthiazoles were identified as potent anti-H. pylori agents, and of these, thienylthiazole derivative 44 exhibited the strongest activity (MIC = 0.0065 mug/mL) among the compounds obtained in our guanidinothiazole studies. Although 44 was void of H2 antagonist activity, pyridylthiazole derivative 39 had both potent anti-H. pylori and H2 antagonist activities. Thiazolylthiazole derivative 46 also showed potent anti-H. pylori activity, but the H2 antagonist activity was weak. On the other hand, no attractive activities were found in pyrimidyl, oxazolyl, isoxazolyl, imidazolyl, and oxadiazolylthiazole derivatives. The anti-H. pylori activity of the aryloxazole analogues was weaker than those of the corresponding arylthiazole derivatives, though they had potent H2 antagonist activity.
