GOSTAR Services

Excelra Knowledge Solutions (EXCELRA), Asia's leading Contract Research Organization, delivers customized data curation services to the life sciences industry. EXCELRA's scientists analyze data to transform biological patterns into knowledge.

Our services in Bio/Chemo-informatics, Structural Biology, Bio-IT and Patent Research are tailor made to suit customer requirements. Our value-added services across the drug discovery chain, from discovery to development have been widely used by major pharmaceutical companies to boost their R&D efforts. In products we have number of databases which are Reference centric as well as Molecule centric. In combination with the products we give value added customized services.


The identification of high quality Hit/lead compounds is a crucial first step in the small molecule drug discovery process. High quality leads are more likely to be successfully optimized into drug candidates that survive the development process. Hit/Leads can be identified through a variety of methods, including high throughput screening (HTS), virtual screening (VS), and literature sources. All these methods are used routinely in large pharmaceutical companies, while smaller biotech that do not have large screening compound collections may rely more on VS and literature. There are two general methods used for virtual screening: structure-based (or target-based) and pharmacophore-based (or ligand-based). The first approach requires knowledge about the target while the second requires knowledge about the ligands. In cases where there is information about both the target and ligands, both techniques can be used in a sequential fashion. With either method, a screening database of compounds is used in the virtual screening process as a source of hits. Virtual screening is a well-established methodology at EXCELRA.
