Viscoelastic Properties of Poly(vinyl methyl ether)

Antitumor activity and some pharmacologic properties of anthramycin methyl ether.

The antitumor antibiotic, anthramycin methyl ether (AME), was shown to be active in increasing survival time in mice bearing various experimental leukemias. Like actinomycin D, it was active against P388 but inactive against P388/38280. AME also was active against the plasma cell tumor LCP, while having no activity against the plasma cell tumor YPC-1. AME bad an IDso of 0.02/~g/ml against L1210...

Desoxyhemigossypol 6-methyl ether

THE TITLE SESQUITERPENE [SYSTEMATIC NAME: 6-methoxy-10-methyl-7-(propan-2-yl)-2-oxatricyclo[6.3.1.0(4,12)]dodeca-1(11),4,6,8(12),9-pentaen-5-ol], C(16)H(18)O(3), was isolated from pathogen-infected stele tissue of Gossypium barbadense. There are two mol-ecules in the asymmetric unit and the dihedral angle between their naphtho-furan systems is 86.48 (2)°. In the crystal, O-H⋯O hydrogen bonds be...

Methyl-n-propyl ether.

ME T H Y L N P R O P Y L ETHER is an isomer of di-ethyl ether and possesses the formula CHs-O(CHI)J-CHJ. The physical properties of the two drugs are similar, and the vapour pressure curve of methyl-n-propyl ether is such that it may be used in the Oxford Vaporizer No. 1 without any alteration in the calibration of the instrument (see Figure). Methyl-n-propyl ether has a very unpleasant pungent...

AN EXPLORATORY INVESTIGATION OF VISCOELASTIC NANOINDENTATION ON POLYVINYL ACETATE By

Lacinilene C 7-methyl ether

The title compound, C16H20O3 [systematic name: 1-hy-droxy-7-meth-oxy-1,6-dimethyl-4-(propan-2-yl)naphthalen-2(1H)-one], is a sesquiterpene isolated from foliar tissues of the cotton plant and is of inter-est with respect to its anti-bacterial properties. Its phenyl ring is ideally planar, and the maximum of deviation in the second ring is 0.386 (3) Å. The hy-droxy group and the methyl group are...
