Homo- or heterodimeric compounds that affect dimeric protein function through interaction between monomeric moieties and protein subunits can serve as valuable sources of potent and selective drug candidates. Here, we screened an in-house dimeric natural product collection, and panepocyclinol A (PecA) emerged as a selective and potent STAT3 inhibitor with profound anti-tumor efficacy. Through cross-linking C712/C718 residues in separate STAT3 monomers with two distinct Michael receptors, PecA inhibits STAT3 DNA binding affinity and transcription activity. Molecular dynamics simulation reveals the key conformation changes of STAT3 dimers upon the di-covalent binding with PecA that abolishes its DNA interactions. Furthermore, PecA exhibits high efficacy against anaplastic large T cell lymphoma in vitro and in vivo, especially those with constitutively activated STAT3 or STAT3^Y640F. In summary, our study describes a distinct and effective di-covalent modification for the dimeric compound PecA to disrupt STAT3 function.

Objective:To investigate the clinical efficacy of Yiqi Yangyin decoction combined with metformin and irbesartan in treating type 2 diabetes complicated by hypertension with qi and yin deficiency syndrome. Methods:A case-control study was performed to retrospectively analyze the clinical data of 92 patients with type 2 diabetes complicated by hypertension with qi and yin deficiency syndrome. These patients received treatment at the First People's Hospital of Huzhou from February 2021 to April 2023. They were divided into two groups, with 46 patients in each group, based on different treatment methods. The control group received metformin and irbesartan, while the observation group was treated with Yiqi Yangyin decoction in addition to the treatment provided to the control group. Both groups underwent treatment for 1 month. The clinical efficacy of the two groups was evaluated, and the changes in traditional Chinese medicine symptom scores, blood glucose levels, blood pressure, and the occurrence of adverse reactions were compared between the two groups before and after treatment. Results:The total response rate of the observation group was 93.48% (43/46), which was significantly higher than that of the control group [82.61% (38/46), χ2 = 5.63, P < 0.05). After treatment, the traditional Chinese medicine symptom score for the observation group was (9.43 ± 2.11) points, which was significantly lower than that of the control group [(12.11 ± 2.32) points, t = 11.34, P < 0.001]. The fasting blood glucose, 2-hour postprandial blood glucose, and glycosylated hemoglobin levels in the observation group were (7.51 ± 1.34) mmol/L, (9.06 ± 2.11) mmol/L, and (6.23 ± 0.76)%, respectively, all of which were significantly lower than those in the control group [(8.75 ± 2.12) mmol/L, (11.15 ± 2.43) mmol/L, (7.11 ± 1.02)%, t = 4.13, 6.14, 4.01, all P < 0.05]. The systolic blood pressure in the observation group was (125.48 ± 8.14) mmHg (1 mmHg = 0.133 kPa), which was significantly lower than that in the control group [(131.32 ± 9.22) mmHg, t = 6.76, P < 0.001]. The difference in the incidence of adverse reactions between the two groups was not statistically significant ( P > 0.05). Conclusion:Yiqi Yangyin decoction combined with metformin and irbesartan is highly effective in treating type 2 diabetes complicated by hypertension with qi and yin deficiency syndrome. This combined therapy can effectively lower the traditional Chinese medicine symptom score, improve patients' blood glucose and blood pressure levels, and has a low incidence of adverse reactions.

Objective:To investigate the correlation between serum forkhead box protein P1 (FOXP1) and cyclin-dependent kinase2 (CDK2) and bone mineral density in perimenopausal women with osteoporosis (OP) .Methods:A total of 80 perimenopausal women treated in our hospital from Feb. 2021 to Aug. 2022 were selected as study objects. Among them, 38 were in the OP group and 42 were in the control group. The expression levels of FOXP1 and CDK2 in serum were detected by ELISA. BMD expression levels of lumbar spine (L1-L4) and femoral neck were measured by DEXA BMD analyzer. The correlation between serum FOXP1 and CDK2 and bone mineral density in perimenopausal women with osteoporosis was analyzed by Pearson method.Results:Compared with the control group, the contents of FOXP1 and CDK2 in serum of the control group were (42.94±3.37) pg/ml and (102.46±12.247) pg/ml, respectively. Serum FOXP1 and CDK2 contents in OP group were (25.91±4.38) pg/ml and (60.59±10.777) pg/ml, respectively. Compared with the control group, serum FOXP1 and CDK2 expression levels and bone mineral density of lumbar spine (L1-L4) and femoral neck in OP group were significantly decreased. The BMD of lumbar spine (L1-L4) and femoral neck of women in the control group were 0.68±0.28 and 0.43±0.99, respectively. BMD of lumbar spine (L1-L4) and femoral neck of women in the OP group were 0.40±0.10 and 0.21±0.15, respectively. Bone mineral density decreased in the lumbar spine (L1-L4) and femoral neck in the OP group. The differences were statistically significant ( P<0.05). In addition, the correlation analysis results showed that the expression level of FOXP1 in serum was positively correlated with bone mineral density of lumbar spine (L1-L4) and femoral neck ( r=0.546, 0.245, P<0.05), and the expression level of CDK2 was positively correlated with bone mineral density of lumbar spine (L1-L4) ( r=0.600, P<0.05) . Conclusions:In perimenopausal women with osteoporosis, the expression of FOXP1 and CDK2 in serum was significantly decreased, and there was a correlation with bone mineral density. It is suggested that FOXP1 and CDK2 may be used as biological indicators and clinical predictors of osteoporosis in perimenopausal women.
