  • Publication number: 20080167220
    Abstract: Methods are disclosed for inhibiting or disrupting Janus tyrosine kinase 3 (Jak3) dependent function in cells of lymphoid or myeloid origin, especially for blocking proliferation and function of lymphocytes (e.g., T-cells, B-cells). A Mannich base compound, or a derivative or modified compound, is employed which is capable of selectively inhibiting Jak3 while affecting other protein tyrosine kinase activities to a lesser extent or not at all, to provide beneficial effects such as mitigation of transplant rejection and alleviation of allergic responses with fewer side effects than with conventional immunosuppressive agents.

  • Patent number: 7238366
    Abstract: This invention provides an aqueous/t-butanol solvent-system, facile reconstitute, submicron-reconsitiute preliposome-lyophilaye and method of its preparation and use. In one embodiment this entails a modified method for the preparation of a submicron and stable liposome formulation of the non-cross-resistant anthracycline Annamycin is described. The optimal lipid composition was DMPC:DMPG at a 7:3 molar ratio and the optimal lipid:drug weight ratio 50:1. The selected formulation is a preliposome lyophilized powder that contains the phospholipids, Annamycin, and 1.7 mg Tween 20 per mg of Annamycin. The liposome suspension is obtained on the day of use by adding normal saline at 37° C. (1 ml per mg Annamycin) and hand-shaking for one minute. The presence of Tween 20 is essential in shortening the reconstitution step (from >2 hours to 1 minute), avoiding the early formation of free drug crystals, and reducing the median particle size (from 1.5 ?m to 0.15-0.20 ?m) without destruction of the liposome vesicles.
