摘要:
Carbapenems of the formula ##STR1## wherein: P' is a removable protecting group for hydroxy; and M is a removable protecting group for carboxy; are useful intermediates for carbapenem antibiotics.
摘要:
This invention provides novel β-lactamase inhibitors of the aryl- and heteroaryl-sulfonamidomethylphosphonate monoester class having nitrogen-based cations or quarternary ammomium groups. The compounds inhibit three classes of β-lactamases and synergize the antibacterial effects of β-lactam antibiotics (e.g., imipenem and ceftazimdime) against those micro-organisms normally resistant to the β-lactam antibiotics as a result of the presence of the β-lactamases.
摘要:
The present invention relates to compounds and derivatives thereof, their cynthesis, and their use as estrogen receptor modulators. The compound of the instant invention are ligands for estrogen receptors and as such may be useful for treatment or prevention of a variety of conditions related to estrogen functioning including: bone loss, bone fractures, osteoporosis, cartilage degeneration, endometriosis, uterine fibroid desease, hot flashes, increased levels of LDL cholestterol, cardiovascular disease, impairment of cognitive functioning, cerebral degenerative disorders, restenosis, gynecomastia, vascular smooth muschle cell proliferation, obesity, incontinence, and cancer, in particular of the breast, uterus and prostate.
