In part, the present disclosure relates methods for treating, preventing, or reducing the severity of a myeloproliferative disorder (e.g., polycythemia vera, essential thrombocythemia, and myelofibrosis) or one or more complications of a myeloproliferative disorder. The present disclosure further relates methods for treating, preventing, or reducing the severity of a Janus kinase-associated disorder or one or more complications of a Janus kinase-associated disorder. In certain aspects the disclosure provides TβRII antagonists for treating, preventing, or reducing the severity of a myeloproliferative disorder (e.g., polycythemia vera, essential thrombocythemia, and myelofibrosis) or a Janus kinase-associated disorder or one or more complications of a myeloproliferative disorder or a Janus kinase-associated disorder.

The invention relates to a novel medicine for treating leukemia and a preparation method thereof and belongs to the technical field of traditional Chinese medicines. The medicine is prepared into different preparations by the conventional method in the following steps: by taking taxus chinensis, sculellaria barbata, oldenlandia diffusa, trigone, curcuma zedoary and silkworm bombycis as main materials and cleavers, American ginseng, prismatomeria tetrandra, isatis roots, tuber fleeceflower stems, Tupistra fimbriata Hand.Mazz., fructus corni, lucid ganoderma, human placenta, ligusticum wallichii and turtle shells as auxiliary materials, dosing; drying; respectively grinding fine powder; uniformly mixing; and then steaming and basking for three times. As taxus chinensis contains the No.1 anti-cancer drug in world: paclitaxel and the auxiliary materials assist, growth and development of cancer cells can be controlled, the anticancer ability of human body is boosted, and meanwhile, cyclic and metabolic functions of the human body can be further enhanced, so that viruses accumulated in the human body are eliminated outside by diuresis and defecation so as to realize the effect of treating leukemia. According to clinical trails, the total effective rate is over 90%. The medicine has the best curative effect on acute myelocytic leukemia, myelodysplastic syndromes and graft-versus-host disease, the second effect on polycythemia vera and chronic myelognous leukia, and then acute promyelocytic leukemia.

The present invention relates to a pyrrolopyrimidine five-membered azacyclic derivative as a novel JAK kinase inhibitor, and use thereof in a preparation of a pharmaceutical product for preventing and / or treating an indication related to a JAK kinase function. The pyrrolopyrimidine five-membered azacyclic derivative of the invention is an ideal JAK kinase inhibitor with a high potency, and can be used to treat or prevent diseases such as rheumatoid arthritis, polycythemia vera, psoriasis, primary thrombocytosis, myelofibrosis, and the like. The pyrrolopyrimidine five-membered azacyclic derivative has the general formula of formula I

The present invention discloses the signaling pathway involved in erythroid repression by iron deficiency. Further disclosed is a non-toxic small-molecule compound which potently reverses the erythroid repression caused by iron deficiency. The present invention further encompasses novel compounds for inhibition of red cell production, useful, for example, in the treatment of polycythemia vera, a malignancy causing uncontrolled red cell production. These inhibitory compounds also promote megakaryocytic lineage commitment and may therefore be useful for augmentation of platelet production. The present invention further discloses isocitrate reversal of iron deprivation.
