1,4-Dihydroxy-5,8-bis(((2[(2-hydroxyethyl)amino]ethyl)amino))-9,-10-anthracenedione dihydrochloride (CL 232315; NSC 301739D), a representative of a new chemical class of compounds with antineoplastic properties, has been evaluated for antitumor activity in experimental mouse tumor systems. The compound produced significant increases in life span (ILS) and long-term survivors when tested against the P388 and L1210 leukemias as well as the solid neoplasms, B16 melanoma and Colon Tumor 26. The optimal treatment regimens resulted in a 173 to greater than 200% ILS with 20 to 80% 60-day survivors in mice with P388 leukemia, A 205% ILS with 55% 60-day survivors in mice with L1210 leukemia, and an ILS of greater than 300% with 80% 90-day survivors in mice with B16 melanoma. In contrast to Adriamycin, CL 232315 was active against the i.v. implanted L1210 leukemia and demonstrated moderate activity against P388/Adria, a subline of P388 resistant to Adriamycin. The compound was ineffective when tested against the Lewis lung carcinoma and the Ridgway osteogenic sarcoma. CL 232315 was active i.p., s.c., and i.v., but p.o. activity was not demonstrated. Schedule dependency was not observed when the compound was administered once daily for nine days, once every four days, or as a single dose.

The antimetabolite antibiotic L-(alphaS,5S)-alpha-amino-3-chloro-4,5-dihydro-5-isoxazoleacetic acid (AT-125) showed significant antitumor activity against L1210 and P388 mouse leukemias and the M5076 mouse ovarian tumor. Depending on the schedule of administration, increases in lifespan of greater than 100% were observed. Activity was observed after ip, oral, or sc inoculation of AT-125 in mice inoculated with L1210 by the ip route. Lewis lung carcinoma and B16 melanoma were not affected by AT-125. The compound was used to treat human tumor xenografts in athymic (nude) mice. The MX-1 mammary tumor regressed when treated with either 8 or 16 mg/kg/day for 10 days, while a dose of 32 mg/kg was toxic. On an every-4-days x 3 schedule there was a marked slowing of MX-1 tumor growth at 50, 100, and 200 mg/kg. The LX-1 lung tumor xenograft growth was slowed significantly by a dose of 32 mg/kg. Growth of colon tumors, CX-1, CX-2, and CX-3, was not affected by AT-125.

A new model is presented for the study of the effects of supranormal temperatures on human tumors in vivo. Human tumors heterotransplanted serially in nude mice were heated in vivo by means of local radio-frequency heating. A lung carcinoma, a breast carcinoma, a colon carcinoma, and a malignant melanoma were studied. The tumors were transplanted s.c. in the inguinal area or under the kidney capsule of adult nude mice. The s.c. tumors were heated for 30 min. Temperatures of 43--44 degrees C were reached in the surrounding normal tissues, whereas in the center of the tumor temperatures of 46--49 degrees C were recorded. In 11 of 16 randomized pairs of mice, the growth of the tumor treated by hyperthermia was inhibited by 75% or more as compared with the growth of the untreated tumor control. No mortality and only temporary damage to skin and muscle were observed. The kidney tumors were also treated for 30 min, but it was possible to reach only 40 degrees C in the abdomen. Seventy-five % mortality was observed. Of seven randomized pairs evaluated, five exhibited a reduction of growth varying from 37 to 63%9 The model proposed appears to be a workable and promising one, especially for s.c. growing tumors.

A novel nitrosourea derivative, methyl-6-[[[(2-chloroethyl)nitrosoamino]carbonyl]-amino]-6-deoxy-alpha-D-glucopyranoside (MCNU), is a water-soluble compound in which a methoxyl group is attached to the C-1 position and an N-(2-chloroethyl)-N-nitrosoureido group is attached to the C-6 position of the glucose moiety. MCNU exhibited a marked life-prolongation or growth-inhibitory effect against mouse L1210 leukemia, adenocarcinoma 755, Nakahara-Fukuoka sarcoma, Lewis lung carcinoma, and B16 melanoma. Ip, oral, or iv administration of MCNU was markedly effective against L1210 leukemia, and the therapeutic ratio by ip administration was larger than that of chlorozotocin or CCNU. The life-prolongation effect of MCNU against established Lewis lung carcinoma was similar to that of methyl-CCNU. The bone marrow toxicity of MCNU was less than that of CCNU but considerably more than that of chlorozotocin.

The sensitivity to local tumor hyperthermia (43 degrees, 60 min) of a spectrum of eight different solid mouse tumors (Lewis lung carcinoma, M5076 ovarian carcinoma, colon carcinoma 38, colon carcinoma 26, mammary adenocarcinoma C3HBA, mammary adenocarcinoma 16C, glioma 26, and B16 melanoma) was investigated. A microwave (2.45-GHz) apparatus produced localized heating of the tumors without generation of whole-body hyperthermia. The temperature at the center of the heated tumors was regulated to within +/- 0.1 degrees while the temperature uniformity within the tumor was +/- 0.5 degrees. The local hyperthermia treatments reduced the size and retarded the growth of the treated tumors compared with control values for each of the tumors tested. The faster-growing Lewis lung carcinoma and B16 melanoma were the least responsive to treatment, while the slower-growing colon 38 and M5076 ovarian carcinomas were the most responsive. Multiple treatments resulted in longer grwoth delays and greater tumor growth inhibition than did single treatments. No consistent difference in life span between the control and treated groups was measured, and only five of 188 treated animals were cured.

The chemotherapeutic activity of analogs of the anthracycline antibiotic, nogalamycin, was investigated in the P388 and L1210 leukemias and the B16 melanoma in mice. Among the compounds tested, 7-con-O-methylnogarol was found to have superior activity. Depending on the route and schedule of administration, increases in lifespan (ILS) in excess of 100% were observed in all three tumor systems. Additional testing of 7-con-O-methylnogarol demonstrated significant activity in the murine colon 26 and colon 38 tumors and the CD8F1 mammary tumor. 7-Con-O-methylnogarol was not significantly effective against murine Lewis lung carcinoma, although ILSs of 38% and 29% were achieved in two experiments. Activity was observed against ip inoculated P388 leukemia after ip, sc, oral, and iv drug administration. 7-Con-O-methylnogarol was also highly active (ILS greater than or equal to 120%) after ip drug administration to mice with iv inoculated P388 leukemia. Significant ILS values resulted from a variety of schedules of administration against ip inoculated P388 leukemia and B16 melanoma. Experiments in which the time of single-dose administration was varied prior to the time of ip P388 leukemia inoculation showed that residual drug or bioactive drug-related materials remained in mice for 8 hours after 50 mg/kg administered ip and for 48 hours after 200 mg/kg administered sc.

Screening for retinoic acid-binding protein (RABP) in experimental tumors revealed the presence of this protein in three mammary tumors, two metastatic colon tumors, B16 melanoma. Lewis lung carcinoma, Ridgway osteogenic sarcoma, and keratoacanthoma. RABP was below the limits of detection in two weakly metastatic colon tumors and in Sarcoma 180. After s.c. implantation of RABP-containing tumors into mice, this protein could be traced in the lungs due to pulmonary metastasis. Following implantation of Lewis lung tumors, RABP was detected in the lung on the 6th day. On the 15th day after implantation, RABP was present in lung and brain, but not in other tissues where this protein was normally lacking. In primary cultures of Lewis lung carcinoma, the lower limit for detection of RABP by sucrose gradient sedimentation technique corresponded to 0.12 mg protein that was extractable from 3 X 10(5) cells. Both chick embryo skin and rabbit ear skin extracts contained RABP; the level of cellular retinol-binding protein was high in chick embryo skin but only marginal in rabbit ear. The amounts of these proteins on chick embryo skin and rabbit ear skin correlate with the biological potency of retinol and retinoic acid, as observed by others.

The effect of chronic ethanol intake on the growth and spread of some murine tumors has been investigated. The treatment had no effect on the B 16 melanoma but tended to decrease the number of Ehrlich ascites cells. In the case of the Lewis lung carcinoma, administration of ethanol for two weeks tended to lower the number of metastases to the lung without significantly affecting the primary tumor size, whereas more prolonged ethanol intake decreased the weight of the primary tumor in addition to decreasing its dissemination.

The character of metastasis of 9 strains of transplantable mouse tumours in conventional subcutaneous inoculation was studied. There were differences in the frequency, intensity, and types of metastasis of different tumours. Periods of onset of metastases of Lewis lung carcinoma and RL-67, and also of sarcoma-37 were established. Sarcoma, Lewis and RL-67 lung carcinomas, adenocarcinoma of the colon AKATOL, Cloudman's melanoma and B-16 metastasized most intensively. Sarcoma-37 metastasizing into the regional and remote lymph nodes, Lewis lung carcinoma and melanomas metastasizing into the lungs, RL-67 lung carcinoma metastasizing into the lungs, kidneys, adrenal glands, ovaries, the heart, and also adenocarcinoma of the colon AKATOL metastasizing into the lymph nodes and the liver can be used as models for the research in the field of drug action upon metastases and the metastasis process.

The chemotherapeutic effects of 6-diazo-5-oxo-L-norleucine (DON) and N-[N-gamma-glutamyl-6-diazo-5-oxo-norleucinyl]6-diazo-5-oxo-norleucine (azotomycin) were evaluated in a spectrum of transplantable experimental tumor systems including xenografts of human tumors in athymic mice. Both drugs displayed remarkable activity against the murine leukemia L1210 and P388, the Colon Tumors C26 and C38 and the CD8F1 mammary tumor. No significant activity was observed against Lewis lung carcinoma, B16 carcinoma, B16 melanoma, and intracranial ependymoblastoma. DON and azotomycin also exhibited striking inhibitory effects on the growth of s.c. human tumor (MX-1 mammary, LX-1 lung and CX-1 and CX-2 colon) xenografts in athymic mice. With the exception of one colon xenograft (CX-1), all tumor lines were markedly responsive to both drugs. Tumor regressions below the initial tumor sizes of 100 to 300 mg, albeit temporary, were brought about by one course of treatment every 4 days for 3 doses (at optimal dose) with either drug. Although these drugs have been tested previously in the clinic and have shown only limited therapeutic effectiveness, they seem to worthy of a second and closer look in light of the recent laboratory results.
