We aimed to determine capacity and readiness of Australian clinical genetic healthcare professionals to provide genomic medicine. An online survey was administered to individuals with genetic counseling or clinical genetics qualifications in Australia. Data collected included: education, certification, continuing professional development (CPD), employment, and genetic versus genomic clinical practice. Of the estimated 630 clinical genetic healthcare professionals in Australia, 354 completed the survey (56.2% response rate). Explanatory interviews were conducted with 5.5% of the genetic counselor respondents. Those working clinically reported being involved in aspects of whole exome or genome sequencing (48.6% genetic counselors, 88.6% clinical geneticists). Most genetic counselors (74.2%) and clinical geneticists (87.0%) had attended genomics CPD in the last two years, with 61.0% and 39.1% self-funding, respectively. Genetic counselors desire broad involvement in genomics, including understanding classifying and interpreting results to better counsel patients. The majority of respondents (89.9%) were satisfied with their job and 91.6% planned to work in genetics until retirement. However, 14.1% of the genetic counselors in clinical roles and 24.6% of the clinical geneticists planned to retire within 10 years. This is the first national audit of clinical genetic healthcare professionals, revealing the Australian workforce is motivated and prepared to embrace new models to deliver genomic medicine but consideration of education and training is required to meet demand.

A series of piperazine derivatives were designed and synthesised as gp120-CD4 inhibitors. SAR studies led to the discovery of potent inhibitors in a cell based anti viral assay represented by compounds 9 and 28. The rat pharmacokinetic and antiviral profiles of selected compounds are also presented.

A major problem associated with non-nucleoside reverse transcriptase inhibitors (NNRTIs) for the treatment of HIV is their vulnerability to mutations in the allosteric binding site of reverse transcriptase that can result in the development of a resistant virus. Herein we present the optimization of a series of 5-aryloxy imidazoles, which possess a balanced pharmacological profile against both wild-type enzyme and the clinically relevant mutations K103N and Y181C. Subtle structural changes were used to probe structure-activity relationships relating to both potency and metabolic stability, which led to an imidazole derivative with an impressive overall profile.

The synthesis and structure-activity relationship of a series of novel gp120-CD4 inhibitors are described. Pharmacokinetic studies and antiviral spectrum assessment of lead compounds led to the identification of compound 36, a potent gp120-CD4 inhibitor which exhibited antiviral potency across a spectrum of 25 clade B isolates.

In the present article, we describe SAR studies within a series of N-hydroxy-dihydronaphthyridinone HIV integrase inhibitors that led to a candidate compound, PF-4776548, of high potency and with an excellent resistance profile. Uncertainties around the human pharmacokinetic predictions for PF-4776548 led to the compound being taken into a human microdose study to confirm its human pharmacokinetics, the results of which are described herein.
