FTY720 treatment resulted in significant prolonged survival in a xenograft severe combined immunodeficiency mouse model of disseminated B-cell lymphoma/leukemia, providing the first evidence for the potential use of FTY720 as a therapeutic agent in a variety of B- cell malignancies, including CLL.

The three-dimensional structure demonstrates that the B ring of R-bicalutamide in the W741L mutant is accommodated at the location of the indole ring of Trp-741 in the WT AR bound to dihydrotestosterone.
Flavopiridol administered using a pharmacologically derived schedule is associated with marked clinical efficacy in refractory, genetically high-risk chronic lymphocytic leukemia.
Flavopiridol administered using this novel schedule has significant clinical activity in refractory CLL and other diseases, and patients with bulky disease and high-risk genetic features have achieved durable responses, thereby justifying further study of flavopirIDol.

Meta-analyses indicate that testosterone supplementation increases fat-free mass and muscle strength in HIV-positive men with weight loss, glucocorticoid-treated men, and older men with low or low-normal testosterone levels, and selective androgen-receptor modulators that are preferentially anabolic hold promise as anabolic therapies.
Structural Basis for Accommodation of Nonsteroidal Ligands in the Androgen Receptor*

- 11 November 2005
These studies provide the first crystallographic evidence of the mechanism by which nonsteroid ligands interact with the wild type AR and provide critical new insight for receptor-based drug design of nonsteroidal AR agonists and antagonists.
Pharmacodynamics of Selective Androgen Receptor Modulators

- 1 March 2003
Compounds S-1 and S-4 were identified as SARMs with potent and tissue-selective in vivo pharmacological activity, and represent the first members of a new class of SAR Ms with selective anabolic effects.
