The present invention relates to a new, essentially four-step process for preparing beta-L-2′-deoxy-thymidine starting from L-arabinose. The process according to the invention is particularly important for mass production of beta-L-2′-deoxy-thymidine.
This invention relates to certain novel compounds and derivatives thereof, their synthesis, and their use as alpha 1a adrenergic receptor antagonists. One application of these compounds is in the treatment of benign prostatic hyperplasia. These compounds are selective in their ability to relax smooth muscle tissue enriched in the alpha 1a receptor subtype without at the same time inducing hypotension. One such tissue is found surrounding the urethral lining. Therefore, one utility of the instant compounds is to provide acute relief to males suffering from benign prostatic hyperplasia, by permitting less hindered urine flow. Another utility of the instant compounds is provided by combination with a human 5-alpha reductase inhibitory compound, such that both acute and chronic relief from the effects of benign prostatic hyperplasia are achieved.

Certain novel substituted diazepine sulfonamides are ligands of the human bombesin receptor and, in particular, are selective ligands of the human bombesin receptor subtype-3 (BRS-3). They are therefore useful for the treatment, control, or prevention of diseases and disorders responsive to the modulation of BRS-3, such as obesity, and diabetes.
