Stereospecific C6-hydroxyethylation of the penicillin nucleus.
Sir: Recent discoveries of potent jl-lactam antibiotics possessing a hydroxyethyl moiety instead of the usual amido side chain at C6 have stimulated the interest in synthetic methods for obtaining hydroxyethyl penicillanates.1) Convenient method for the preparation of 6-hydroxyethyl penicillanate by using metal-halogen exchange reaction was reported earlier by DININNO, et al.2) As an extension ...
متن کاملThe crossing number of C6 × Cn
It is proved that the crossing number of C6 X Cn is 4n for every n 2: 6. This is in agreement with the general conjecture that the crossing number of Cm x en is (m 2)n, for 3 ::; m :s; n.
متن کاملC6: synthesis by the liver in vivo
The allotype of the sixth component of complement was determined in a patient before and after liver transplantation. The C6 phenotype changed from A before transplantation to B (the donor phenotype) within 10 days of the transplant and remained wholly of the donor phenotype at 17 wk. This demonstrates that the liver is the exclusive or predominant site of C6 synthesis in vivo in man.
متن کاملMusculocutaneous Nerve Lesion (C5-C6)
Lesions of the nerve produce weakness of flexion at the elbow and weakness of supination. The biceps is an important supinator. There is sensory loss on the lateral side of the forearm. The brachialis muscle receives innervation from both the musculocutaneous nerve and the radial nerve. [7] [8] One study found that the musculocutaneous nerve contributes to 42% of the muscle power that flexes th...
