Bioorthogonal Chemistry – Making Drugs Inside Patients – And More

From the 27 March 2012 article at Medical News Today

The traditional way of making medicines from ingredients mixed together in a factory may be joined by a new approach in which doctors administer the ingredients for a medicine separately to patients, and the ingredients combine to produce the medicine inside patients’ bodies.

That’s one promise from an emerging new field of chemistry, according to the scientist who founded it barely a decade ago. Carolyn Bertozzi, Ph.D., spoke on the topic – bioorthogonal chemistry – delivering the latest Kavli Foundation Innovations in Chemistry Lecture at the 243rd National Meeting & Exposition of the American Chemical Society (ACS).

Bertozzi explained that the techniques of bioorthogonal chemistry may fundamentally change the nature of drug development and diagnosis of disease, so that the active ingredients for medicines and substances to image diseased tissue are produced inside patients.

“Suppose a drug doesn’t reach diseased tissue in concentrations high enough to work,” Bertozzi said, citing one example of the potential of the new chemistry. “Maybe it is an oral drug that doesn’t get absorbed very well into the blood through the stomach. You can imagine a scenario in which doctors administer two parts of the molecule that makes up the drug. …

“Too much ownership of data and secrecy involved”

From the 21 March 2012 article by Gary Schwitzer at HealthNewsReviews.org

That’s what one author writes in a series of papers published in Circulation: Cardiovascular Quality and Outcomes this month addressing issues involving the integrity of research data.

Yale’s Harlan Krumholz writes: “Patients facing a decision deserve information that is based on all of the evidence.”  Further excerpt:

Every day, patients and their caregivers are faced with difficult decisions about treatment. They turn to physicians and other healthcare professionals to interpret the medical evidence and assist them in making individualized decisions.

Unfortunately, we are learning that what is published in the medical literature represents only a portion of the evidence that is relevant to the risks and benefits of available treatments. In a profession that seeks to rely on evidence, it is ironic that we tolerate a system that enables evidence to be outside of public view. Those who own data, usually scientists or industry, have the choice of what, where, and when to publish. As a result, our medical literature portrays only a partial picture of the evidence about clinical strategies, including drugs and devices. Experts have recently drawn attention to this issue, including contributions in this issue of our journal, but there is resistance to change….

The article goes on outline how sharing of clinical trial and research data could be shared for the common good.
