摘要:
The Chlorambucil derivatives are novel compounds having the formula (I). ##STR1## wherein R represents a hydrogen atom or an acyl group such as ##STR2## and n is 1 or 2. The Chlorambucil derivatives can be produced by binding Chlorambucil to hydroxyl group at 17-position of estradiol or its derivative in the presence of a binding agent selected from the group consisting of compounds having the formulaX(CH.sub.2).sub.n COOHX(CH.sub.2).sub.n COXHOOC(CH.sub.2).sub.n COOH andXOC(CH.sub.2).sub.n COXwherein n is 1 or 2 and X represents a halogen atom.

A process for producing a steroid hormone-antitumor derivative which selectively affects to tumor or cancer cells comprises reacting X group of a steroid hormone derivative having the formula ##STR1## wherein ST represents a steroid moiety having a cyclophenanthrene hydrocarbon skeleton of gonane, estrane or androstane which is bound to carboxyl group by esterifying OH group on D ring with carboxyl group; and R' represents a C.sub.1 -C.sub.4 alkylene group and X represents a halogen atom, amino group, hydroxyl group, carboxyl group or a salt thereof, with a modified or non-modified reactive group of an antitumor drug to form a binded group of ##STR2##

摘要:
Conjugates of amino sugar-steroid hormone are prepared by binding an amino sugar to steroid hormone at 3- or 17-position by a direct reaction or by binding with a binding agent, and the conjugate is useful in an enzyme immunoassay method.

1,1-DI-(2,7 OCTADIENEOXYMETHYLENE)-1-(HYDROXYMETHYLENE)ALKANE PREPARED BY REACTING TRIMETHYLOL COMPOUNDS WITH BUTADIENE, USING A CATALYST CONSISTING OF PALLADIUM COMPOUNDS, ALKALI METAL SALTS OF WEAK ACIDS AND PHOSPHINES, SAID ALKANE BEING IMPORTANT AS A CHEMICAL INTERMEDIATE IN MANUFACTURING LUBRICATING OILS AND PAINTS.
摘要:
Disclosed is a method for producing the high-quality mycelia of the Basidiomycetes from culture thereof by promoting growth of the fungus as well as differentiation of the cells and attendant organization thereof by adding to the culture medium a straight chain saturated aliphatic alcohol with a catbon number within a specified range of 26 to 36 carbon atoms.
