The present invention relates to 6,19-epidioxy-9,10-secocholesta-5(10),7-diene-1α,3β,25-triol represented by formula (). The vitamin D 3 derivative represented by the formula () of the present invention is a new compound and is produced by photosensitizing oxidation of 1α,25-dihydroxyvitamin D 3 . Photosensitized oxidation can be used, for example, to convert 1α,25-dihydroxyvitamin D3 into methanol, ethanol,
Rose Bengal in an organic solvent such as propanol,
A halogen lamp while introducing oxygen or air in the presence of an organic dye such as eosin or methylene blue,
This is done by irradiating a device that emits visible light, such as a tungsten lamp. It is preferable that the irradiation period is continued until the raw material 1α,25-dihydroxyvitamin D 3 disappears. The compound () of the present invention is isolated from the reaction mixture by a conventional method, for example, by distilling off the solvent and subjecting the mixture to column chromatography or the like. Compound of the present invention obtained in this way ()
has two optical isomers due to the asymmetric carbon atom at the 6-position, specifically (6R)-6,19-epidioxy-

1α,3β,25-triol and (6S)-6,19-
epidioxy-9,10-secocollector-5 (10),
It is divided into 7-diene-1α, 3β, 25-triol. Both of these are human osteopathic leukemia HL.
It is a compound that has a very strong ability to induce differentiation into granulocytes in -60 cells and is useful as a cancer removal agent. Experimental example Human osteopathic leukemia cell line HL-60, 100U/ml
of penicillin, 100 μg/ml streptomycin , and 10% fetal calf serum inactivated by heat treatment at 37° C. and 5% CO 2 /air. HL-60 cells were grown to 1×10 5 cells/ml and cultured with the compounds of the present invention at concentrations of 50 ng/ml and 100 ng/ml. The ability to induce differentiation (appearance of C3 receptor and phagocytic ability) was measured after culturing for 3 days. C3 receptor detection is
Phagocytosis was determined according to the method of Lotem & Sachs (Int. J. Cancer 15 , 731) and the method of Collins et al. (Proc. Natl.
Acad.Sci.USA. 75 , 2458). The results are shown in the table below.

[Table] The symbols in the compound column in the table correspond to the symbols of each compound described in Examples below. Example 1 840 μg of α,25-dihydroxyvitamin D 3 and 20 mg of rose bengal were dissolved in 15 ml of pharmacopoeial ethanol, and after inhaling oxygen gas, the mixture was irradiated with light using a 200 W halogen lamp for 1.5 hours. After the reaction solvent was distilled off under reduced pressure, the residue was purified by column chromatography using silica gel, resulting in two isomers with different coordination at the 6-position and different polarity [150 μg of weakly polar compound (a)] , a highly polar compound (b)
