“Bicycles and Tricycles” [PDF]

Nature, 1897
IN reading Mr. Boys' most interesting review of Mr. Sharp's book on “Bicycles and Tricyles” (NATURE, July 8), a few points occur to me as requiring further notice.

Adverse drug reactions associated with amitriptyline - protocol for a systematic multiple-indication review and meta-analysis [PDF]

, 2020
Background: Unwanted anticholinergic effects are both underestimated and frequently overlooked. Failure to identify adverse drug reactions (ADRs) can lead to prescribing cascades and the unnecessary use of over-thecounter products.

6-[(tert-Butyldimethylsilyl)oxy]-3-ethenyl-7-methoxy-4-[(trimethylsilyl)ethynyl]naphtho[2,3-c]furan-1(3H)-one

IUCrData, 2020
The tricyclic core in the title compound, C26H34O4Si2, shows disorder of the furan ring and deviates slightly from planarity, with the largest displacement from the least-squares plane [0.166 (2) Å] for the major disordered part of the methine C atom. To

Synthesis of fused tricyclic amines unsubstituted at the ring-junction positions by a cascade condensation, cyclization, cycloaddition then decarbonylation strategy

Beilstein Journal of Organic Chemistry, 2012
Heating aldehydes that contain a protected hydroxymethyl group, a tethered alkyl chloride and a tethered alkenyl group at the α-position of the aldehyde with an amine sets up a cascade (tandem) reaction sequence involving condensation to an intermediate ...

Photochemical Approaches to Complex Chemotypes: Applications in Natural Product Synthesis. [PDF]

, 2016
The use of photochemical transformations is a powerful strategy that allows for the formation of a high degree of molecular complexity from relatively simple building blocks in a single step. A central feature of all light-promoted transformations is the

Identification of Trypanosoma cruzi Polyamine Transport Inhibitors by Computational Drug Repurposing [PDF]

, 2019
Trypanosoma cruzi is the causative agent of Chagas disease, a parasitic infection endemic in Latin America. In T. cruzi the transport of polyamines is essential because this organism is unable to synthesize these compounds de novo.

Synthesis of Tricyclic Condensed Rings Incorporating the Pyrazole or Isoxazole Moieties Bonded to a 4-Piperidinyl Substituent

Molecules, 2013
In this paper we report the synthesis of new compounds based on the pyrazole and isoxazole framework fused to a cycloalkene unit, and bearing as a substituent the 1-piperidinyl group as new examples of potential antipsychotic molecules.

Synthesis of fused tricyclic peptides using a reprogrammed translation system and chemical modification [PDF]

, 2015
Here we report a unique method of ribosomally synthesizing fused tricyclic peptides. Flexizyme-assisted in vitro translation of a linear peptide with the N-terminal chloroacetyl group and four downstream cysteines followed by the addition of 1,3,5-tris ...
