Definitions
- the present invention relates to novel compounds which have hemoregulatory activities and can be used to stimulate haematopoiesis and for the treatment of viral, fungal and bacterial infectious diseases.
- the haematopoietic system is a life-long cell renewal process whereby a defined stem cell population gives rise to a larger population of mature, differentiated blood cells (Dexter TM. Stem cells in normal growth and disease, Br Med J 1987; 195: 1 192-1194) of at least nine different cell lineages (erythrocytes, platelets, eosinophils, basophils, neutrophils, monocytes/macrophages, osteoclastes and lymphocytes) (Metcalf D. The Molecular Control of Blood Cells, 1988; Harvard University Press, Cambridge, MA). The stem cells are also ultimately responsible for regenerating the bone marrow following treatment with cytotoxic agents or following bone marrow transplantation.
- the risk of infection is directly related to the degree of myelosuppression as measured by the severity and duration of neutropenia (Brody GP, Buckley M, Sathe YS, Freireich EJ. Quantitative relationship between circulating leukocytes and infections with acute leukemia. Ann In Med 1965; 64:328-334).
- the control of haematopoiesis involves the interplay of a variety of cytokines and growth factors during various stages of the haematopoietic cascade, including early pluripotent stem cells and mature circulating effector cells.
- G-CSF granulocyte colony stimulating factor
- GM-CSF granulocyte- macrophage stimulating factor
- M-CSF macrophage-colony stimulating factor
- G-CSF granulocyte colony stimulating factor
- G-CSF granulocyte- macrophage stimulating factor
- M-CSF macrophage-colony stimulating factor
- interleukines which have overlapping, additive and synergistic actions which play major roles in host defence. Mechanistically, this is accomplished by enhancing the production of granulocytes and macrophages, as well as by the activation of effector cell functions (Moore MAS. Haematopoietic growth factor interactions: in vitro and in vivo preclinical evaluation. Cancer Surveys 1990; 9:7-80).
- These co-ordinated activities support optimal host defences which are necessary for fighting bacterial, viral and fungal infections.
- G-, GM- and/or M-CSF may reduce the duration of neutropenia, accelerate myeloid recovery and reduce neutropenia-associated infections and other infectious complications in patients with malignancies who are receiving cytotoxic chemotherapy or in high infectious-risk patients following bone marrow transplantation (Steward WP. Granulocyte and granulocyte-macrophage colony stimulating factors, Lancet 1993; 342: 153-157 and Munn DH, Cheung NKV. Preclinical and clinical studies of macrophage colony- stimulating factor. Semin Oncol 1992; 19:395-407).
- This invention comprises compounds, hereinafter represented as Formula (I), which have hemoregulatory activities and can be used to stimulate haematopoiesis and in the prevention and treatment of bacterial, viral and fungal diseases.
- These compounds are useful in the restoration of leukocytes in patients with lowered cell counts resulting from a variety of clinical situations, such as surgical induced myelosuppression, AIDS, ARDS, congenital myelodysplacis, bone marrow and organ transplants; in the protection of patients with leukopenia from infection; in the treatment of severely burned patients and in the amelioration of the myelosuppression observed with some cell-cycle specific antiviral agents and in the treatment of infections in patients who have had bone marrow transplants, especially those with graft versus host disease, in the treatment of tuberculosis and in the treatment of fevers of unknown origin in humans and animals.
- the compounds are also useful in the treatment and prevention of viral, fungal and bacterial diseases, particularly Candida, Herpes and hepatitis in both immunosuppressed and "normal" subjects.
- This invention is also a pharmaceutical composition, which comprises a compound of Formula (I) and a pharmaceutically acceptable carrier.
- This invention further constitutes a method for stimulating the myelopoietic system of an animal, including humans, which comprises administering to an animal in need thereof, an effective amount of a compound of Formula (I).
- This invention also constitutes a method for preventing and treating viral, fungal and bacterial infections including sepsis, in immunosuppressed and normal animals, including humans, which comprises administering to an animal in need thereof, an effective amount of a compound of Formula (I).

No unacceptable toxicological effects are expected when compounds of the invention are administered in accordance with the present invention.
- the murine bone marrow derived from stromal cell line C6.4 is grown in 12 well pates in RPMI 1640 with 10% FBS. Upon reaching confluence, the C6.4 cells are washed and the media exchanged with fresh RPMI 1640 without FBS. Confluent cell layers of murine C6.4 cells are treated with compound. Cell free supernatants are collected 18 hours later. Supernatants are fractionated with a Centricon-30 molecular weight cut-off membrane. C6.4 cell hematopoietic synergistic factor (HSF) activity is measured in a murine CFU-C assay. CFU-C Assay
- Bone marrow cells are obtained from C57B 1/6 female mice and suspended in RPMI 1640 with 10% FBS. Bone marrow cells (7.5E+4 cells/mL) are cultured with sub optimal levels of CFU plus dilutions of test C6.4 cell 30K-E supernatants from above in a standard murine soft agar CFU-C assay. Cell aggregates >50 cells are counted as colonies. The number of agar colonies counted is proportional to the amount of HSF present within the C6.4 bone marrow stromal line supernatant.

- nmoles of cytochrome c reduced /well is calculated from spectrophotometric readings (550 nm) taken following a 1 hour incubation at 37 °C (5% CO2).
- the amount of SOD-inhibitable cytochrome c reduced is determined by the inclusion of wells containing SOD (200 U/well). Baseline superoxide release is determined in the absence of stimuli. Experimental data are expressed as a percentage of the control group. Examples
- Example 1 Preparation of ⁇ , ⁇ '-bis(picolinoyl-seryl)-[cyc/ ⁇ -(D-Lys-L-Lys)]
- the resulting cyc/ ⁇ -[D-Lys-L-Lys] was suspended in DMF (25 mL) and added to a pre-activated (5 min) solution of Z-Se ⁇ Bu ⁇ -OH (153 mg, 0.4 mmol), PyBOP (208 mg, 0.4 mmol), HOBt (54 mg, 0.4 mmol) and NMM (0.13 mL, 1.2 mmol) in DMF (5 mL). The mixture was stirred for 2 h. The resulting clear solution was evaporated and treated with 5 % aq NaHCO3. The precipitated oil was extracted into CH2C12- The extract was washed successively with 10 % aq citric acid and 2 M aq NaCl.
