Sugar&Splice supports PubChem’s support for biologics

Half a million molecules on PubChem have just had a new section added entitled “Biologic Description”. This includes a depiction of the oligomer structure and several line notations including IUPAC condensed and HELM, all of which were generated using Sugar&Splice through perception from the all-atom representation. Since the original development of Sugar&Splice was as part of a collaboration with PubChem, it is great to see these annotations finally appearing as part of this important resource.

Previous blog posts have shown examples of the sorts of peptide depictions that Sugar&Splice can generate. Here is how one appears on PubChem (CID118753634).

Sugar&Splice also supports CFG-style depiction of oligosaccharides (CID71297593):

As ever, there is always more work to be done on improving depictions and perception, and we look forward to further increasing the coverage of biologics in PubChem over the coming months.

PhD positions available in Big Data Analysis in Chemistry

NextMove Software is a partner in theĀ Horizon 2020 MSC ITN EID BigChem project. Ten PhD positionsĀ are available in the area of “Big Data Analysis in Chemistry”, all of which offer a mix of time spent in academia and with industrial partners. The following position involves a placement with us for 3 months:

ESR2: Computational compound profiling by large-scale mining of pharmaceutical data

This position is announced within the BIGCHEM project. Read about the carrier development perspectives.

Check eligibility rules as well as recruitment details and apply for this position before 20 March 2016.

Objectives: In the life-sciences, data is being generated and published at unprecedented rates. This wealth of data provides unique opportunities to get insights into the mechanisms of disease and to identify starting points for treatments. At the same time, the size, complexity and heterogeneity of available data sets pose substantial challenges for computational analysis and design.

Aim of this project is to address the challenges posed by large, heterogeneous, incomplete, and noisy datasets. Specifically, we aim to:

  • apply machine learning technologies to derive predictive QSAR models from real-world life science data sets;
  • analyze trade-offs between training data accuracy and quantity, in particular, in the context of high-throughput screening data;
  • develop and apply methods to systematically account for noise and experimental errors in the search for active compounds.

Planned secondments: Three months stay in NextMove to work with data automatically extracted from patents using unique technology of company. Three months in HMGU to collect data from public databases such as ChEMBL, OCHEM, PubChem.

Employment: 36 months total, including Boehringer Ingelheim, Biberach, Germany (months 1-18) and the University of Bonn, Germany (months 19-36).

Enrollment in PhD program: The ESR will be supervised by Prof. J. Bajorath from the University of Bonn and by supervisors from Boehringer Ingelheim.
