The total number of treatment lines in the late stage ≤3 lines; 9. At least 1 measurable lesion was present according to RECIST1.1; External radiation therapy (EBRT) or local area treatment (such as radiofrequency ablation) of the lesion must show evidence of disease progression (according to RECIST 1.1), can be used as target lesion; 10. Life expectancy ≥3 months; 11. The functional level of the organ must meet the following requirements:

1. Blood routine: ANC≥1.5×109/L (no growth factor used within 14 days); PLT 100 x 109 or higher/L (within 7 daysNo corrective treatment was used); Hb≥100 g/L(no corrective treatment was used within 7 days);
2. Blood biochemistry: TBIL≤1.5×ULN; ALT and AST≤3 x ULN; Glutamine transpeptidase GGT≤2.5×ULN; If liver metastasis exists, ALT and/or AST≤5×ULN; Glutamine transpeptidase GGT≤5×ULN; Urea, urea nitrogen (BUN), creatinine (Cr) ≤1.5×ULN;

11. The time interval between the end of the last antitumor therapy and the first administration of the study drug meets the following requirements: surgery The interval must be ≥4 weeks (minor surgery, such as tumor biopsy, thoracopuncture, or intravenous catheter placement, is not limited); Recovery of adverse reactions to previous antitumor therapy (radiotherapy, chemotherapy, targeting) to ≤ Grade 1 (phase Ib required patients A washout period of 7-14 days after natural recovery without symptomatic drugs or symptomatic treatment).

12. Voluntarily agrees to and signs a written informed consent and is willing and able to comply with all aspects of the test protocol,The patient may withdraw consent at any time without prejudice to his rights and interests.

Exclusion Criteria:

-

Subjects will not be enrolled if they meet any of the following criteria:

1. Receiving neoadjuvant or adjuvant therapy containing Iribulin within one year prior to treatment initiation;
2. Patients with recurrent or metastatic breast cancer who have failed or responded to previous treatment with Iribulin (achieved CR/PR/SD), but tumor progression within 6 months after cessation of aribulin therapy;
3. Patients who have received any HDAC inhibitor at any time in the past;
4. Participated in clinical trials of unmarketed drugs within 4 weeks before enrollment;
5. Exclude subjects with brain or subdural metastases. Unless the patient has completed local treatment and is stable on imaging Those who had maintained the condition for at least 4 weeks, had stopped systemic sex hormone therapy and had stable symptoms for at least 4 weeks were included(By comparing head enhancement CT or MRI performed during screening with head enhancement performed at least 4 weeks earlier CT or MRI to determine the stability of the lesion);
6. Before screening, the toxicity of the original treatment regimen had not recovered, and there were still more than grade 1 toxic reactions (CTCAE5.0);
7. Clinically significant gastrointestinal abnormalities that may affect drug intake, transport, or absorption (e.g., inability to swallow,Chronic diarrhea, intestinal obstruction, etc);

9. Severe cardiovascular injury (greater than NYHA Class II congestive heart failure) History), unstable angina pectoris or myocardial infarction within the past 6 months, or severe arrhythmia;
10. Subjects with allograft requiring immunosuppressive therapy.
11. Subject has active hepatitis (hepatitis B reference: HBsAg positive and HBV DNA≥500 IU/ml; cLiver reference: HCV antibody positive and HCV virus copy number > upper limit of normal); Known human immunodeficiency disease Hiv-positive subjects.
12. Had other malignancies within the previous 5 years, excluding cured papillary thyroid carcinoma and in situ cervix Carcinoma, skin basal cell carcinoma or skin squamous cell carcinoma;
13. Subjects with hypersensitivity to softin B and/or softin B chemical derivatives.
14. Pregnant and lactating women, fertile women who have tested positive for baseline pregnancy tests,or were unwilling to use effective contraception throughout the trial period and within 90 days after the last administration of the study drug age patients;
