 Frequently Asked Questions for New Drug Product Exclusivity
A 5-year period of exclusivity is granted to new drug applications for products containing chemical entities never previously approved by FDA either alone or in combination.
In this context, "new" is intended to convey a lack of prior use of a clinical investigation rather than any temporal requirement.
A new chemical entity means a drug that contains no active moiety that has been approved by FDA in any other application submitted under section 505(b) of the Act.

 Monthly Feature - June 2005 - Nanotechnology Aims to Improve Drug Synthesis
Discovering a new drug to fight cancer is a major accomplishment, but figuring out how to synthesize that drug in large quantities and in pure form can often be as much of a challenge.
Unfortunately, these chemical catalysts are not as specific as their enzymatic counterparts, and as a result, none of the 11 chemical reactions (in the case of tamoxifen's synthesis) is perfect — each chemical step produces the desired chemical and various byproducts that must be removed subsequently; in contrast, enzymes rarely generate byproducts.
Zhou explained that chemical catalysts have always been nanoscale entities, but what is new is that chemists can now control the exact makeup of the catalyst at the atomic and molecular levels.

 Drug development for neglected diseases: a deficient market and a public-health policy failure   (Site not responding. Last check: 2007-10-13)
For the period considered, the number of new chemical entities per million DALYs was 0·55 for infectious and parasitic diseases, compared with values two to three times higher (ranging between 1·25 and 1·44) for the main diseases of the high-income countries.
Overall, the biggest advance in drug research and development and new chemical entity outputs for neglected diseases has been in malaria, for which four new chemical entities have been approved between 1975 and 1999, and 18 projects were in clinical development in 2001.
The new approaches to antimalarial therapies rely mainly on artemisinin derivatives discovered in China in the 1970s, which are particularly effective in combination with other drugs in slowing the development and spread of drug resistance.

 New chemical entity - Wikipedia, the free encyclopedia
A NCE is a chemical molecule developed by the innovator company in the early drug discovery stage, which after undergoing clinical trials could translate into a drug that could be a cure for some disease.
Synthesis of NCE is the first step in the process of development of a drug.
Companies adopting this model of business would be able to generate high margins as they get a huge one-time payment for the NCE apart from entering into a revenue sharing agreement with the licensee company.

 New Indian Patent Law, A Sell Off By Alternative Law Forum
The term chemical ought to have been inserted so as to read any new chemical entity.
The use of the phrase which does not result in the enhancement of the known efficacy is ambiguous, too broad and potentially allows for new forms of existing substances to become patented.
It is quite possible to argue the procedure both ways, therefore, potentially delaying urgent new drugs that a developing or least developing country may require.

 HYLE 4-2 (1998): Modes of Chemical Becoming
The kinds of chemical becoming discussed here may be interpreted to exemplify what a "harmony of features” (Neville 1989) or "fully reciprocal acting” (Leclerc 1972) might mean, and to extend classical ontology in interesting, and perhaps useful, ways.
The fact that some chemical species react while others do not can be understood (in favorable cases) in terms of the chemical bonding (enthalpy) and degree of disorder (entropy) of the reactant and product states.
In both these types of chemical system it is possible to investigate the component species or processes in as much detail as may be desired, so that rather complete understanding of those components can be attained.

 An Introduction to Molecular Modeling
Over the past few years, advances in the development of new mathematical models which describe chemical phenomena and development of more intuitive program interfaces coupled with the availability of faster, smaller and affordable computer hardware have provided experimental scientists with a new set of computational tools.
As the nuclei are moved to new coordinates and molecular energies are re-calculated, a quantitative description of molecular energy is derived.
Each of the methods described above are used to calculate the energy of a compound in a specific 3D orientation and to optimize the geometry as a function of energy (i.e., adjust the coordinates of each of the atoms and recompute the energy of the molecule until a minimum energy is obtained).

The use of biodiversity as source of new chemical entities against defined molecular targets for treatment of malaria, tuberculosis, and T-cell mediated diseases--a review.
The modern approach to the development of new chemical entities against complex diseases, especially the neglected endemic diseases such as tuberculosis and malaria, is based on the use of defined molecular targets.
Chemical diversity is also driven by these forces, in an attempt to best fit the plant communities to the particular abiotic stresses, fauna, and microbes that co-exist with them.

 FasterCures: Biopharmaceuticals: The Innovation Pipeline Race
While there is more corporate oversight and bureaucracy inherent in larger organizations, Dr. O'Bryan-Tear noted that large companies are inherently more risk-averse in their research agendas, as they have more opportunities to fail, based simply on the increased compounds they are researching.
Where they previously provided funds to companies with a promising new chemical entitity, many are waiting for the compounds to reach mid-stage clinical trials, where the investment risk and the time to market are both decreased.
The panelists concluded that, though the investment climate is increasingly risk-averse and new chemical entities face hurdles at every step of the development process, "targeted therapies are the future" and big pharma and small biotechs each possess individual strengths and weaknesses in their research and development protocols.
