A passion for

innovation

We are constantly innovating our people, project management and technology models leading to outstanding results for our collaborators. The world’s first app based technology platform Chemistry in the CloudTM enables us to work together to make faster decisions. Our deep understanding that an early and intensive evaluation of target molecules based on real insight into the science will lead to faster downstream execution. The result is a higher throughput of successful drug-like compounds.

Medicinal chemistry

Medicinal chemistry expertise available at o2h discovery includes hit identification, hit-to-lead optimisation, lead generation, and lead optimisation. All of these can be accessed as stand-alones or as a part of an integrated drug discovery project.

Hit identification/lead generation projects have involved ligand design for customer-defined targets, synthesis of homologous or diverse series of compounds, design and generation of structurally related compounds, combinatorial synthesis of general as well as focused libraries and search for surrogates of core chemical scaffolds.

Hit-to-lead projects typically involve confirmation of a genuine structure-activity relationship (SAR) and reducing structural/pharmacological liabilities. o2h discovery has the capability to synthesise small focused arrays of compounds in sufficient quantities to allow clients to rapidly screen these compounds for ADME and in vitro biological activity (primary as well as secondary screenings).

For projects advancing to lead optimisation phase, chemists at o2h discovery work intensively with their biology counterparts to produce compounds which closely match the desired target product profile. Typically, this involves a thorough search of prior art and assuring patentability, generation of back-up series and leading the compounds to in vivo proof-of-concept. Our biologists can assist in generating in vivo experimental models recapitulating a particular human pathological condition, designing and efficiently executing PK/PD, toxicology and other relevant pharmacological studies to advance these compounds further.

Computational chemists at o2h discovery work at providing stand-alone services to our clients with in silico based screening projects as well as supporting medicinal chemistry projects. Computational chemistry expertise includes molecular modelling, virtual screening and drug designing.

Virtual screening services include target identification, in silico drug-likeness, screening of client/commercial databases to identify focused lead/hit compounds and docking studies to prioritise hits for in vitro studies.

Drug designing to support hit generation and lead optimisation are applied to augment medicinal chemistry design efforts and help guide structural modifications to enhance potency, selectivity and drug-like characteristics. Close cooperation between our molecular modellers and medicinal chemists plays a vital role in this process.

Apart from these, we also support designing target-focused libraries, target modelling, molecular dynamic simulations and developing highly predictive 3D-QSAR models based on target and therapeutic areas.
