Mom will teach you NMR

New Drug Approvals

Dedicated to all moms in the world
C=O group is dad
O atom is mom
Carbonyl is dad and oxygen mom hence c labelled methyl has higher chemical shift  and gets a little more attention

NMR IS EASY
A chemical has Formula: C5H10O2
C5H10O2
Rule 2, omit O, gives C5H10
5 – 10/2 + 1 = 1 degree of unsaturation.
Look for 1 pi bond or aliphatic ring.
IR
IR spectrum
The band at 1740 indicates a carbonyl, probably a saturated aliphatic ester. The bands at 3000-2850 indicate C-H alkane stretches. The bands in the region 1320-1000 could be due to C-O stretch, consistent with an ester.

Abstract Image

Active pharmaceutical ingredients (APIs) are frequently delivered to the patient in the solid state as part of such dosage forms as tablets, capsules, etc.In this context the ability to deliver the drug to the patient in a safe, efficacious and cost-effective way depends largely on the physicochemical properties of the APIs in the solid state, and ……..read more

FDA Issues Draft Guidance on NCE Exclusivity Determinations

New Drug Approvals

Feb 25, 2014
FDA has released draft guidance on the agency’s interpretation of the five-year new chemical entity (NCE) exclusivity provisions as they apply to certain fixed-combination drug products (fixed-combinations).  The guidance document states that FDA, historically, has said that a fixed-combination was ineligible for five-year NCE exclusivity if it contained a previously approved active moiety, even if the product also contained a new active moiety (i.e., an active moiety that FDA had not previously approved).

The guidance states that because fixed-combinations have become increasingly prevalent in certain therapeutic areas (e.g., cancer, cardiovascular, and infectious disease) and play an important role in optimizing adherence to dosing regimens, FDA is revising their interpretation of the five-year NCE exclusivity provisions “to further incentivize the development of certain fixed-combination products.” FDA intends to apply the new interpretation prospectively. The guidance, however, does not apply to fixed-combination drug products that were approved prior to…

Drug discovery

New Drug Approvals

In the fields of medicinebiotechnology and pharmacologydrug discovery is the process by which new candidate medications are discovered.

Historically, drugs were discovered through identifying the active ingredient from traditional remedies or by serendipitous discovery. Later chemical libraries of synthetic small moleculesnatural products or extracts were screened in intact cells or whole organisms to identify substances that have a desirable therapeutic effect in a process known as classical pharmacology. Sincesequencing of the human genome which allowed rapid cloning and synthesis of large quantities of purified proteins, it has become common practice to use high throughput screening of large compounds libraries against isolated biological targets which are hypothesized to be disease modifying in a process known as reverse pharmacology.

Hits from these screens are then tested in cells and then in animals for efficacy. Even more recently, scientists have been able to…

The FDA’s Drug Review Process: Ensuring Drugs Are Safe and Effective

New Drug Approvals

How Drugs are Developed and Approved

The mission of FDA’s Center for Drug Evaluation and Research (CDER) is to ensure that drugs marketed in this country are safe and effective. CDER does not test drugs, although the Center’s Office of Testing and Research does conduct limited research in the areas of drug quality, safety, and effectiveness.

CDER is the largest of FDA’s five centers.   It has responsibility for both prescription and nonprescription or over-the-counter (OTC) drugs. For more information on CDER activities, including performance of drug reviews,  post-marketing risk assessment, and other highlights, please see the CDER Update: Improving Public Health Through Human Drugs The other four FDA centers have responsibility for medical and radiological devices, food, and cosmetics, biologics, and veterinary drugs.

Some companies submit a new drug application (NDA) to introduce a new drug product into the U.S. Market.  It is the responsibility of the company seeking to…

FDA publishes new Guidance on Validation of Analytical Methods

New Drug Approvals

The FDA has published a new Guidance on the validation of analytical methods which shall replace the 14 years old existing Guideline on the topic. More details about the contents of this highly topical document can be found here.

A new FDA Guidance for Industry entitled “Analytical Procedures and Methods Validation for Drugs and Biologics” was published a few days ago. This Guideline replaces the Guidance for Industry “Analytical Procedures and Methods Validation” from 2000 (this document has never been finalised and has had a draft status 14 years long) and – when finalised – should also replace the “Guidelines for Submitting Samples and Analytical Data for Methods Validation” which came into force in 1987.

Unlike the previous Guideline from 2000, the new document explicitly mentions biologics in its title. The objective of the Guideline is to inform applicants about what data are…
