Maribavir (previously known as 1263W94) is a novel benzimidazole riboside compound. This drug was in phase III of clinical trial for the prevention of cytomegalovirus (CMV) infections in transplant patients, sponsored by ViroPharma. However, drug failed to demonstrate a higher efficacy rate than the placebo. Maribavir has activity against cytomegalovirus and Epstein-Barr virus (EBV), but not against other human herpesviruses. Maribavir’s mechanism of action is unique and is complex compared to the currently approved antivirals for CMV. Maribavir inhibits the viral UL97 kinase rather than the viral DNA polymerase. The UL97 kinase is important for viral DNA elongation, DNA packaging, and nuclear egress of encapsidated viral DNA. In addition, maribavir inhibits the EBV DNA polymerase processivity factor (BMRF1), reduces the level of certain EBV glycoproteins, and inhibits viral transcription. However, future work will be designed to address the interaction of MBV and BGLF4 and to evaluate the mechanisms through which maribavir downregulates viral transcripts. BGLF4 belongs to the family of conserved herpesvirus PKs, which includes HCMV UL97, HSV UL13, and HSV US3. Maribavir does need to be phosphorylated for its activity.
Estetrol is the natural human fetal selective estrogen receptor modulator. It is synthesized exclusively by the human fetal liver during pregnancy. Estetrol has a moderate affinity for human estrogen A receptor (ERa) and estrogen B receptor (ERb). Estetrol may be suitable as a potential drug for human use in applications such as hormone replacement therapy (vaginal atrophy, hot flushes), contraception and osteoporosis. The most common drug-related adverse events were lower abdominal pain, nausea, headache, dysmenorrhoea, breast enlargement and acne. Estetrol had been in clinical trials for the treatment of breast and prostate cancers.
Tivozanib (formerly AV-951, KRN-951) is a potent and selective VEGFR tyrosine kinase inhibitor and inhibits angiogenesis and vascular permeability in tumor tissues. It completed phase III a trial investigation for the treatment of renal cell carcinomas, but has not been still approved. In addition, this drug is in the phase II of clinical trial for the investigation it in patients with glioblastoma and colorectal carcinoma.

Fluoroestradiol F-18 is a derivative of estradiol. where hydrogen at position 16 is replaced by radioactive fluorine. Fluoroestradiol F-18 is taken up by tumor cells, expression estrogen receptor, and it is clinically evaluated for PET imaging to detect and stage breast cancer, ovarian cancer, and cancer of uterine endometrium and myometrium.
Sodium artesunate, an artemisinin derivative, is used in malaria treatment. Artesunate, has been licensed in Thailand for the treatment of falciparum malaria since 1990. It is a potent antimalarial drug that can reduce parasitaemia by 90% within 24 h of administration. Sodium artesunate was first isolated in China, it is a water soluble antimalaria used clinically in China.

Vibegron is a selective beta 3 adrenergic receptor (β3AR) agonist that is being developed in Japan jointly by Kyorin Pharmaceutical Co., Ltd and Kissei Pharmaceutical Co., Ltd and in other regions worldwide (except in several other Asian countries) by Urovant Sciences for the treatment of overactive bladder (OAB). Vibegron potently activates human b3AR and increases cAMP levels, with an EC50 of 1.1 nM. Based on results from Japanese phase III trials, vibegron received approval in Japan in September 2018 for this indication. Vibegron, an active ingredient of Beova® Tablets, is a novel once-daily oral treatment for overactive bladder (OAB), acts selectively on the bladder's β3-adrenergic receptor, relaxes the bladder and enhances the urine collection, and consequently improves the symptoms of urgency, urinary frequency and urge urinary incontinence associated with OAB.
Ozanimod (previously known as RPC-1063) is a selective immune-inflammatory modulator of the G protein-coupled receptors sphingosine 1-phosphate 1 and 5, which are part of the sphingosine 1-phosphate (S1P) receptor family. Treatment with S1P receptor modulators interferes with S1P signaling and blocks the response of lymphocytes (a type of white blood cell) to exit signals from the lymph nodes, sequestering them within the nodes. The result is a downward modulation of circulating lymphocytes and anti-inflammatory activity by inhibiting cell migration to sites of inflammation. Ozanimod is currently in phase III clinical trials for the treatment of relapsing multiple sclerosis (RMS) and ulcerative colitis, and also in phase II clinical trials to determine whether it is effective in the treatment of Crohn's disease.

Relebactum sodium (MK-7655) is a piperidine analog 3 that inhibits class A and C β-lactamases (in vitro). It is being investigated for use in treatment of infectious diseases, such as treatment of gram-negative bacterial infections. Its potential as an alternative to existing medicines in the treatment of drug-resistant bacterial infections is being studied. Clinical trials have been conducted and are still ongoing to evaluate the efficacy and safety of relebactum sodium in treatment of intra-abdominal infections, urinary tract infections (such as pyelonephritis), hospital-acquired and ventilator-associated bacterial pneumonias, and gram-negative bacterial infections.
