The coronavirus disease 2019 (COVID-19) pandemic has stimulated tremendous efforts to develop therapeutic agents that target severe acute respiratory syndrome coronavirus 2 to control viral infection. So far, a few small-molecule antiviral drugs, including nirmatrelvir-ritonavir (Paxlovid), remdesivir, and molnupiravir have been marketed for the treatment of COVID-19. Nirmatrelvir-ritonavir has been recommended by the World Health Organization as an early treatment for outpatients with mild-to-moderate COVID-19. However, the existing treatment options have limitations, and effective treatment strategies that are cost-effective and convenient for tackling COVID-19 are still needed. To date, four domestically developed oral anti-COVID-19 drugs have been granted conditional market approval in China. These drugs include azvudine, simnotrelvir-ritonavir (Xiannuoxin), leritrelvir, and mindeudesivir (VV116). Preclinical and clinical studies have explored the efficacy and tolerability of mindeudesivir and supported its early use in mild-to-moderate COVID-19 cases at high risk for progression. In this review, we discuss the most recent findings regarding the pharmacological mechanism and therapeutic effects focusing on mindeudesivir and other small-molecule antiviral agents for COVID-19. These findings will expand our understanding and highlight the potential widespread application of China's homegrown anti-COVID-19 drugs.

PROSPER is an international Phase III trial demonstrating the beneficial role of enzalutamide, an androgen receptor antagonist, in prolonging metastasis-free survival in men with nonmetastatic castration-resistant prostate cancer. The trial showed that the median metastasis-free survival was 21.9 months longer for those treated with enzalutamide (36.6 months) compared to those treated with placebo (14.7 months). Enzalutamide also showed prolonged time to PSA progression, PSA response, and time to initiating additional antineoplastic therapy although overall survival is not yet reached. Enzalutamide is the second antiandrogen (next to apalutamide) that has gained the United States Food and Drug Administration (US FDA) label indication for use in the setting of nonmetastatic castration-resistant prostate cancer.

OBJECTIVE:
To investigate the timing of reaching maximum improvement of the lower urinary tract symptoms (LUTS) in patients with advanced prostate cancer treated with maximal androgen blockade(MAB), and to provide guidelines for the treatment program.
METHODS:
We collected the data of 45 advanced prostate cancer patients complicated with lower urinary tract symptoms who were treated by MAB. The international prostate symptom score (IPSS) and maximum urinary flow rate (Qmax) were selected as indicators reflecting the degree of lower urinary tract symptoms and were observed before the MAB, 3, 6, and 9 months after the patients received MAB. We also observed the changes of prostate volume and analyzed the role of MAB in improving LUTS in patients with prostate cancer.
RESULTS:
The IPSS and Qmax had significant difference between the 3rd month after the patients received MAB and before the MAB (P<0.05). No significant difference was found between the 3rd month and the 6th month after the patients received MAB (P>0.05). The prostate volume had significant difference in the 3rd month and the 6th month (P<0.05), but no significant difference in the 6th month and the 9th month (P>0.05).
CONCLUSION
MAB for patients with advanced prostate cancer can improve their lower urinary tract symptoms, whose main effect is presented in the 3rd months after the androgen deprivation therapy.

OBJECTIVETo observe the therapeutic effect and safety of vildagliptin combined with insulin aspart injection in elderly patients with type 2 diabetes.
METHODSSixty-six elderly patients with type 2 diabetes who had poor blood glucose control with insulin aspart injection were divided into two groups to have additional Vildagliptin (50 mg, twice daily, n=36, observation group) or Acarbose (50 mg, three times a day, n=30, control group). Blood glucose (including FBG and 2hPG), HbA1C, fasting c-peptide, postprandial c-peptide, BMI and GFR were observed after 12 weeks.
RESULTSIn the observation group, FBG, 2hPG and HbA1C decreased significantly (P<0.05), fasting and postprandial c-peptide increased (P<0.05), and BMI and GFR showed no obvious changes (P>0.05). In the control group, 2hPG and HbA1C were significant lowered (P<0.05) but FBG, fasting and postprandial c-peptide, BMI or GFR showed no changes (P>0.05). Compared with those in the control group, FBG in the observation group showed a significant reduction (P<0.05), but no significant differences were found in 2hPG, HbA1C, BMI or GFR (P>0.05). No hypoglycemia occurred in the two groups during the treatment.
CONCLUSIONVildagliptin with insulin aapart injection has equivalent effect with Acarbose combined with insulin aspart injection in decreasing 2hPG and HbA1C without increasing the body weight or the risk to hypoglycemia or causing lowered GFR. Vildagliptin has better effect in decreasing FBG and improving the function of the islet cells.

8.FK778, A Synthetic Malononitrilamide.
William E FITZSIMMONS ; M Roy FIRST
Yonsei Medical Journal 2004;45(6):1132-1135
FK778 is a synthetic malononitrilamide (MNA) that has been demonstrated to have both both immunosuppressive and anti-proliferative activities. The MNAs inhibit both T-cell and B-cell function by blocking de novo pyrimidine synthesis, through blockade of the pivotal mitochondrial enzyme dihyroorotic acid dehydrogenase (DHODH), and the inhibition of tyrosine kinase activity. FK778 has been demonstrated to prevent acute allograft rejection in multiple experimental transplant models in rodents, dogs and primates and to be effective in the rat model of chronic renal allograft rejection. In addition, FK778 has been shown to prevent vascular remodeling after mechanical intimal injury via a mechanism which may be related to tyrosine kinase inhibitory activity in vascular smooth muscle cells. Another intriguing activity of the MNA family is the ability to block replication of members of the Herpes virus family with in vitro evidence that of efficacy against cytomegalovirus (CMV) and polyoma virus, important pathogens in the transplant recipient. FK778 is currently being explored in a number of trials in solid organ transplant recipients.

This study aimed to evaluate the efficacy of random-start controlled ovarian stimulation (COS) in cancer patients for emergency fertility preservation. In this retrospective comparative study, 22 patients diagnosed with cancer and 44 infertile women undergoing conventional in vitro fertilization (IVF) were included. In cancer patients, ovarian stimulation was started on the day of referral, irrespective of their menstrual cycle date. The control group was selected by age matching among women undergoing conventional IVF. COS outcomes were compared between groups. The number of total and mature oocytes retrieved and the oocyte maturity rate were higher in the random-start group than in the conventional-start group. However, duration of ovarian stimulation was longer in the random-start group (11.4 vs. 10.3 days, P = 0.004). The addition of letrozole to lower the estradiol level during COS did not adversely affect total oocytes retrieved. However, oocyte maturity rate was lower in cycles with letrozole than in cycles without letrozole (71.6% vs. 58.2%, P = 0.019). Our study confirms the feasibility and effectiveness of random-start COS in cancer patients.
