HOT Communication: Enhancing the clinical performance of tadalafil through crystal engineering

Pharmaceutical cocrystals of tadalafil with methylparaben, propylparaben and hydrocinnamic acid were investigated.

Pharmaceutical cocrystals of tadalafil with methylparaben, propylparaben and hydrocinnamic acid were investigated.

A team from the United States report their study on the hydrogen bonding motifs in tadalafil cocrystals with the aim to produce a drug with enhanced solubility for better oral drug absorption.  Tadalafil, currently used for the treatment of erectile dysfunction, is being explored as a treatment for pulmonary arterial hypertension so would be more useful for this application if the time taken to reach its peak plasma concentration was shorter.

To find out more, download this CrystEngComm communication today…

Hot Communication: Selective co-crystal formation to remove impurities

Kay Huai-Ying Hsi and colleagues from Massachusetts Institute of Technology detail a strategy for using co-crystallization as a purification method that could be developed for use during the synthesis and manufacturing of pharmaceutical substances and fine chemicals.

This communication will be published as part of a themed issue on crystal engineering and crystallography in the pharmaceutical industry later in the year.  It’s currently free so do take a look!

Call for papers: Ionic Liquids Themed Issue

We are pleased to announce an upcoming themed issue focussing on ionic liquids, with guest editors Mark Muldoon, Peter Nockemann and Cristina Lagunas-Castedo based at Queen’s University, Belfast. It is our pleasure to invite you to contribute to this themed issue.

The unique physical and chemical properties of ionic liquids as solvents and the potential to tune and control these properties by selecting the appropriate cations and anions, make ionic liquids remarkably versatile for many applications. Recent publications demonstrate their increasing impact on crystal engineering, on materials and nanoscale synthesis, as well as for crystallisation processes.

Contributions in both experimental and theoretical aspects are most welcome. Ideally, contributions should be within the scope of a) the use of ionic liquids as solvents for crystallisation processes; b) ionic liquids for the synthesis of nanocrystalline materials and porous materials; c) the use of ionic liquids for co-crystallisation or crystal structures of ionic liquid salts (including pharmaceutically relevant compounds and metal-containing ionic liquids); d) theoretical studies (for example understanding solid/liquid phase transitions).

How to submit?

All types of manuscript, Communications, Full Papers and Highlights will be considered for publication. We aim to publish this themed issue in late summer 2012 and therefore would like to receive manuscripts by 8th February 2012. The manuscript should be prepared according to the format for regular articles and should be submitted via our online system. All invited manuscripts will be subjected to the normal refereeing procedure.

Deadline for Submission: 8th February 2012

Please indicate on submission that your manuscript is intended for this themed issue and direct any questions to the CrystEngComm Editorial Office.

We invite you to also check out previous themed issues featuring in CrystEngComm. Read them here now.

Establishing mechanisms of solid state double [2 + 2] photochemical reactions

A double [2 + 2] photochemical reaction of 1,5-bis(4-pyridyl)-1,4-pentadiene-3-one (1P) was observed with in four co-crystal forms of 1P with the hydrogen bonding template molecule phloroglucinol (PG) or 5-methoxy resorcinol (MR). 1H NMR and the UV-vis spectroscopic studies established a stepwise mechanism for this reaction through the formation of a monocyclobutane intermediate.
