It has been over twenty years since Lipinski published his work determining the properties of drug molecules associated with good solubility and permeability. Since then, there have been a number of additions and expansions to these “rules”. There has also been keen interest in the application of these guidelines in the drug discovery process and how these apply to new emerging chemical structures such as macrocycles.

This symposium will bring together researchers from a number of different areas of drug discovery and will provide a historical overview of the use of Lipinski’s rules, as well as looking to the future and how we use these rules in the changing drug compound landscape.


Features of the Meeting

  • Historical look at the use of the Rule of Five

  • New parameters used in drug discovery

  • Look forward to the next 20 years

  • Panel discussion in each session

  • Poster session

Who should attend

This meeting is of interest to scientists of any level of experience from academia and industry.

Call for Poster Abstracts

Applications for poster presentations were invited within the theme of historical use of the Rule of Five or looking forward and beyond the Rule of Five.  Posters will be displayed throughout the day. The closing dates for submissions were:

  6th October - poster

  30th June - oral.

Venue and Travel
Address:  Innovation Building, Sygnature Discovery, BioCity, Pennyfoot Street, Nottingham NG1 1GF.   Please download a site plan (showing car park) here.



By train

East Midlands airport is just 20 minutes away, and regular trains run direct from London (journey time two hours).  Sygnature Discovery is just over half-a-mile from the railway station. 


Leave the railway station following signage for trams. After passing through the barriers, turn right onto Station Street, turn left at Jury's onto London Road. At the roundabout, bear right onto Lower Parliament Street (A6008) towards MachineMart, turn right at MachineMart onto Pennyfoot Street. Enter second building on the right (white with green stripes) with black Innovation Building sign outside (postcode NG1 1GF) - about 12 minutes' walk.


By car

There is no car parking for visitors at the venue, BioCity.


Instead the nearest car park (run by the city council) is immediately behind the Innovation Centre, Motorpoint Arena.  Further information about charges may be found here, and you should buy your ticket from the machine.  Here is a site plan showing the car park location.
