Discovery Chemistry

Medicinal chemistry and pharmaceutical chemistry services:

Immunocure offers medicinal chemistry and pharmaceutical chemistry services for all the drug discovery projects in different therapeutic areas. These services are the intersection of organic chemistry synthesis, various biological aspects, and pharmacology. This has to be dealt with an interdisciplinary approach which starts with hit identification, hit to lead and followed by lead optimization. Medicinal chemistry decisions are the most vital part of the discovery that will drive the programs safely in every single step. For better performance a variety of conditions has to be considered such as potency, stability, selectivity, polypharmacology, bioavailability, efficacy and safety. To decide the patentability of a program, medicinal chemistry has a major role in understanding the broad spectrum of chemical space. Our infrastructure facilities can help you to achieve better results in very less time. Our team which has wide experience in all the above characteristics and Immunocure is a better option for all the types of discovery programs.

Medicinal chemistry services are designed as per the client requirements, but in general have the following steps.

  • Design and synthesis: Designing of the synthetic route is critical before proceeding for synthesis. Our highly experienced team has the capability for designing better synthetic routes which are optimal and give high amounts of yield and purity.
  • In-silico Collaboration: Computational chemistry capabilities of the company is an added advantage to the discovery programs. These are used for better optimization of the molecules.
  • In-vitro & In-vivo collaboration: Based on the results from in-vitro and in-vivo, molecules can be further optimized to perform better in the further process.

Immunocure will reduce the iterations in designing, synthesis and biological evaluation of a program and will accelerate discovery with high quality.

Asymmetric synthesis and transformations

Immunocure understood that most of the building blocks in chemistry have a high degree of chirality and various enantiomers will often react differently.

  • Understanding the complexity of the project, discovery chemistry team at Immunocure can synthesize any compound by choosing the stereoselective or stereospecific reactions that favours the construction of chiral molecules.
  • In dealing with the asymmetric transformations the chiral pool synthesis or chiral auxiliary approaches will be undertaken for the better results.

  • Immunocure organometallic chemistry capabilities include the usage of organohalides, lithium metals, boronic acids preparation, C-C, C-N, C-O coupling and heterocycles synthesis from organometallic intermediates.

Focused library synthesis

Immunocure delivers eminent focus library synthesis services to accelerate different stages of discovery projects for the clients. Capable of designing small (25-50) to medium (50-150) sized custom libraries with in-house computational capabilities. The knowledge-based approach in designing focused libraries of Immunocure achieved improved physicochemical properties, pharmacokinetic properties and evaded toxicology allied worries at diverse phases of discovery projects. This approach has given a boost to many discovery projects and improved confidence by enhancing the chance of moving the project from one stage to the other.

Focused library design follows the following criteria to deliver better results for the customers.

  • Designs may be based on the in-house scaffold collections or based on the clients’ scaffold. Different enumeration techniques will be used for increasing the probability of success.
  • Different parameters like molecular weight, ClogP, number of acceptors and donors, rotatable bonds etc, in the initial stages and solubility, permeability, toxicity in the later stages will be considered for maximum diversity of the library.
  • Diverse linked ring systems, chiral scaffolds, fused ring systems, spiro and bicyclic systems will be considered for the better results.
  • Huge collection of chemical space will be considered for novelty and this gives value to the clint in enjoying the intellectual property right without much clashes.

Natural product analogue synthesis

In the interface of chemistry and biology, natural products will be honored initial points in the hunt for extremely specific and effective chemical moieties of better biological endpoints. The team at Immunocure has an overview of innovative concepts and approaches that were used for natural product synthesis. This made us meet the challenges and complications in natural product analog synthesis. Difficulties in reagents supply and lack of strategies for structural modifications of natural product analogs will not stop Immunocure in delivering optimum results to its clients.

To simplify and rationalize the synthesis of natural product analogs, Immunocure will follow different strategies.

  • Starting from the simplest route of designing a natural product analogue by modification of its functional groups, Immunocure will use diverted total synthesis (DTS) for structural modifications in which modified building blocks plays a major role.
  • Function oriented synthesis will be used for some natural products in particular if they were derived from marine sources. The goal of Immunocure is the design simple analogues of natural products where the action is adjusted towards the envisioned application and client interest.
  • Based on the concept that the scaffolds of the natural products and their substructures will have intended biological properties, team at Immunocure can comfortably synthesize natural product analogues.
