Danoprevir, a potent, selective inhibitor of HCV NS3/4A protease, has a short half-life in humans. Therefore, the feasibility of a controlled release (CR) formulation to allow less frequent dosing...
Optimism in a time of pessimism.
Back in 1974, Stewart Brand’s advice was to “stay hungry, stay foolish,” as a way of bringing a beginner’s mind to new challenges. He still follows that advice, and he now says, “The phrase allows you to open your mind and explore. It means putting aside the explanations provided by social constructs and ideologies.”
Semi-mechanistic PK/PD Model of the Effect of Odanacatib, a Cathepsin K Inhibitor, on Bone Turnover to Characterize Lumbar Spine and Distal Forearm Bone Mineral Density in a Phase IIb Study of Postmenopausal Women
Odanacatib (MK-0822), a potent, orally-active inhibitor of cathepsin K, is under clinical development for treatment of postmenopausal osteoporosis. This poster describes base model development of a…

In the same way that the guillotine concentrates the senses, the need to improve productivity in the pharmaceutical industry has become a life-or-death imperative. Improving productivity does not mean working harder and faster while doing the same job as before. Improving productivity lies in innovation—in the technology and processes that clever minds bring into existence. Moreover, what this innovation must accomplish is vividly clear. We must reduce the time and cost of drug development; increase the probability of successful experiments; and bring better drugs to the marketplace.
Simulating the Disposition of Triamcinolone Acetonide following Oral and Pulmonary Administration
Absorption, distribution and clearance of triamcinolone acetonide (TA) from oral and pulmonary administrations have been simulated using GastroPlus™,1. Simulation of orally administered doses and swallowed…
Simulation of human intravenous and oral pharmacokinetics of 21 diverse compounds using physiologically based pharmacokinetic modelling
The importance of predicting human pharmacokinetics during compound selection has been recognized in the pharmaceutical industry. To this end there are many different approaches that are applied.
Why don’t computer systems help me as much as I think they should?
Answer: We don’t really understand the requirements of the process.

A Model of Threshold Behavior Reveals Rescue Mechanisms of Bystander Proteins in Conformational Diseases
Conformational diseases result from the failure of a specific protein to fold into its correct functional state. The misfolded proteins can lead to the toxic aggregation of proteins.
Scientific workflows – the knowledge-generating engines of R&D.
Scientific research requires two kinds of effort. One is the generation and synthesis of original ideas by skilled practitioners. This is a desirable and often lauded talent that can spawn remarkable innovations in science and medical care. The second kind of effort is less visible, but equally important—the hard work required to turn an idea into reality. Executing the experiments, analyzing the data, and developing presentations of results are examples of this work. Although these latter efforts are necessary, and even enjoyable, they nonetheless can be tedious, time-consuming, and expensive.

A Semi-mechanistic Approach to PK/PD Modeling of Complex Response Data: Bone Turnover Example for Odanacatib, a Cathepsin K Inhibitor
A variety of approaches can be taken to incorporate greater mechanistic understanding into PK/PD models, including a variety of bottom-up, middle-out, and top-down approaches. The osteoporosis field…
Black tea improves attention and self-reported alertness
Tea has previously been demonstrated to better help sustain alertness throughout the day in open-label studies.
Productivity is not a four letter word.
For me, anyway, the point of opinion writing is less to try to shape events, a presumptuous and foolhardy ambition at best, than to help stimulate debate and, from my particular perspective, try to explain why things got the way they are and what they might mean and where they might lead. My own idiosyncratic bent as a writer, no doubt a legacy of my years spent in the theater, is to look for a narrative in the many competing dramas unfolding on the national stage.

Astronomy picture of the day.
During the time that I was a clinical pharmacology fellow with Lewis Sheiner and Stuart Beal in San Francisco, the Voyager mission [1] was sending back incredible images of the moons of Jupiter and the rings of Saturn.
