Functional analysis of leishmania cyclopropane fatty acid synthetase [PDF]

open access: yes, 2012
The single gene encoding cyclopropane fatty acid synthetase (CFAS) is present in Leishmania infantum, L. mexicana and L. braziliensis but absent from L. major, a causative agent of cutaneous leishmaniasis. In L.

The Synthesis of Single Enantiomers of α-Mycolic Acids of Mycobacterium­ tuberculosis and Related Organisms, with Alternative­ Cyclopropane Stereochemistries

open access: yesSynOpen, 2017
We report the synthesis of three stereoisomers of a mycolic acid from Mycobacterium tuberculosis containing a di-cis-cyclopropane and of two stereoisomers of a mycolic acid containing a proximal trans-cyclopropane and a distal cis-cyclopropane.

Antiviral Cyclopropane Acids from Deep-Sea-Derived Fungus Aspergillus sydowii

open access: yesMarine Drugs, 2022
Four novel monocyclic cyclopropane acids, namely, sydocyclopropanes A–D (1–4), along with one known congener hamavellone B (5), were isolated from the Aspergillus sydowii MCCC 3A00324 fungus, which was isolated from the deep-sea sediment.

Cyclopropane-Derived Peptidomimetics. Design, Synthesis, and Evaluation of Novel Ras Farnesyltransferase Inhibitors

open access: yes, 2016
Trisubstituted cyclopropanes have previously been established as rigid replacements of dipeptide arrays in several biological systems. Toward further evaluating the utility of these dipeptide mimics in the design of novel CA1A2X-based inhibitors of Ras ...

3,4,5,6,7,8,9-Heptachlorophenaleno[1,9-bc]pyrazole

open access: yesMolbank, 2009
Treatment of perchloro-7H-cyclopropano[a]acenaphthylene 1 with hydrazine hydrate in DMF at ca. 80 °C gives the new 3,4,5,6,7,8,9-heptachlorophenaleno[1,9-bc]pyrazole 2 in 69% yield. This compound is the first example of a phenalene fused pyrazole.

Um estudo teórico de propriedades moleculares em complexos de hidrogênio trimoleculares C2H4···2HF, C2H2···2HF e C3h6···2HF A theoretical study of molecular properties of C2H4···2HF, C2H2···2HF AND C3H6···2HF trimolecular hydrogen-bonded complexes

open access: yesQuímica Nova, 2008
We present a theoretical study of molecular properties in C2H4···2HF, C2H2···2HF and C3H6···2HF trimolecular hydrogen-bonded complexes. From B3LYP/6-311++G(d,p) calculations, the most important structural deformations are related to the C=C (C2H4), C ...

Ball-and-stick models of the cyclopropane molecule

open access: yes, 2022
   Cyclopropane, also called trimethylene, is an explosive, colourless gas. Cyclopropane is nonirritating to mucous membranes and does not depress respiration. Induction of and emergence from cyclopropane anesthesia are usually rapid and smooth.

1‐Azabicyclo[1.1.0]butanes (ABBs) on the Map: Mechanistic Pathways for Catalytic Ring Opening and Functionalizations

open access: yesAngewandte Chemie, EarlyView.
Catalytic strain‐release ring opening and functionalizations of 1‐azabicyclo[1.1.0]butanes (ABBs) represent a promising strategy for accessing diverse azetidine products. These transformations proceed via polar pathways, radical pathways, and hybrid mechanisms that combine both.

The Structures of Cyclopropane−Amine van der Waals Complexes

open access: yes, 2016
The rotational spectra of the cyclopropane−trimethylamine (CYC·TMA) and cyclopropane−dimethylamine (CYC·DMA) complexes have been observed using a pulsed nozzle, Fourier transform microwave spectrometer.
