Acteoside (verbsacoside) is the one of the main active phenylethanoid glycosides from Cistanche deserticola, Lantana camara and some others herbs. It is known to have antioxidant and neuroprotective activity, and herbs containing it are used to enhance memory and can be studied for the treatment of Alzheimer's disease. It is known, that amyloid fibrils accumulation in cerebral can easily lead to neurodegenerative disorders. Acteoside has been reported to inhibit Aβ42 aggregation by activating nuclear translocation of the transcription factor NF-E2-related factor 2 (Nrf2), increasing heme oxygenase-1 (HO-1) expression. It has also been shown that acteoside could decrease nitric oxide synthase (NOS) activity and caspase-3 expression. Acteoside is a natural antioxidant product unlike other anti-tumor compounds, is an inhibitor of protein kinase C (PKC). In addition Reh-acteoside, a general acteoside of Rehmannia leaves was studied in phase 2/3 clinical trials for patients with IgA nephropathy.

Shikonin is a major naphthoquinone compound found in the roots of Lithospermum erythrorhizon and exhibits powerful anticancer activities for various cancer cells. Shikonin and its derivatives are characterized by a wide spectrum of antibacterial activities: high antibacterial activity towards Gram-positive bacteria (Staphylococcus aureus et al.), a stable fungicidal effect towards Candida and Trichosporon fungi. Shikonin normalizes the production of the key mediators of inflammation IL-1 and IL-2, IFN-γ, reduces vascular permeability in the focus of inflammation, exhibiting a marked anti-inflammatory effect. Combined therapy with applications of a bio-polymeric film with shikonin and its esters (naphthoquinone derivatives) led to an obvious improvement of the clinical parameters and reduced the morphological signs of the buccal mucosal lesions. The drug was well tolerated by all patients and no side effects were recorded. Shikonin, as a naturally occurring, low-molecular-weight pan-chemokine receptor inhibitor, constitutes a basis for the development of novel anti-HIV therapeutic agents.

PK-11195 is a selective antagonist of the Translocator Protein (TSPO). The C11 radiolabeled isotope of PK-11195 ([11C]-(R)-PK-11195) has been used effectively for diagnostic PET imaging in a number of CNS conditions where imaging of TSPO is informative (the S- enantiomer is not used). Applicable conditions including Schizophrenia, Multiple Sclerosis, and Traumatic Brain Injuries where it has been particularly useful for detection of increased microglial activation. It has also been investigated as means to monitor the role of Toll-Like Receptor-4 (TLR-4) after cerebral ischemia in mice. It should be noted that the unlabeled PK-11195 had been investigated for a number of potential therapeutic uses but did not progress beyond animal and cell models.

Daprodustat (DUVROQ) is a small molecule inhibitor of hypoxia-inducible factor prolyl hydroxylase (PHD) developed by GlaxoSmithKline for the treatment of anaemia in patients with chronic kidney disease (CKD). Inhibition of PHD prevents degradation of hypoxia-inducible factor (HIF), leading to the production of erythropoietin and subsequent induction of erythropoiesis. In June, daprodustat received its first approval in Japan for the treatment of renal anaemia.

Omidenepag isopropyl, a prodrug, is hydrolyzed in the eye to the active form (Omidenepag) which functions as a selective, nonprostaglandin, prostanoid EP2 agonist, has been developed by Ube Industries and Santen Pharmaceutical as an ophthalmic solution (EYBELIS®) for the treatment of glaucoma and ocular hypertension. Omidenepag isopropyl increases the outfow of aqueous humor via both the uveoscleral outfow and the trabecular outfow pathways, resulting in potent and stable reduction in intraocular pressure (IOP). In September 2018, omidenepag isopropyl ophthalmic solution 0.002% was approved in Japan for the treatment of glaucoma and ocular hypertension. On September 22, 2022, the FDA approved Santen’s Omlonti (omidenepag isopropyl), for the reduction of elevated intraocular pressure in patients with open-angle glaucoma or ocular hypertension.

Mobocertinib (EXKIVITY™) is a first-in-class EGFR tyrosine kinase inhibitor being developed for the treatment of EGFR exon 20 insertion (EGFRex20ins) -positive non-small cell lung cancer (NSCLC). Mobocertinib is a kinase inhibitor of the epidermal growth factor receptor (EGFR) that irreversibly binds to and inhibits EGFR exon 20 insertion mutations at lower concentrations than wild type (WT) EGFR. Two pharmacologically-active metabolites (AP32960 and AP32914) with similar inhibitory profiles to mobocertinib have been identified in the plasma after oral administration of mobocertinib. In vitro, mobocertinib also inhibited the activity of other EGFR family members (HER2 and HER4) and one additional kinase (BLK) at clinically relevant concentrations (IC50 values <2 nM). Based on efficacy in patients whose disease had progressed on or after platinum-based therapy in a phase I/II trial, mobocertinib was recently granted accelerated approval in the USA in this indication. The drug is also being assessed for marketing approval in various other countries and territories including the EU and China.

Umbralisib (Ukoniq, TG Therapeutics) is an orally available PI3K delta inhibitor, targeting the delta isoform with nanomolar potency and several fold selectivity over the alpha, beta, and gamma isoforms of PI3K. The delta isoform of PI3K is strongly expressed in cells of hematopoietic origin and is believed to be important in the proliferation and survival of B-cell lymphocytes. On February 5, 2021, the Food and Drug Administration granted accelerated approval to umbralisib for the following indications: adult patients with relapsed or refractory marginal zone lymphoma (MZL) who have received at least one prior anti-CD20-based regimen; adult patients with relapsed or refractory follicular lymphoma (FL) who have received at least three prior lines of systemic therapy. However, on June 1, 2022, the FDA withdrew its approval for the cancer medicine Ukoniq due to safety concerns.

Abametapir is a newly FDA-approved, single-application treatment for head lice in patients aged 6 months and older. Abametapir chelates heavy metal cations and inhibits metalloproteinases critical to louse ova development, hatching, and adult survival. Abametapir lotion, 0.74%, demonstrated significant ovicidal activity against head lice eggs with a single application.

Allopregnanolone is a neurosteroid metabolite of progesterone. It is an allosteric modulator of inhibitory γ-aminobutyric acid (GABA-A) receptors on neural stem cells and other cell types in the brain. Allopregnanolone has effects similar to those of other positive allosteric modulators of the GABA action at GABAA receptor such as the benzodiazepines, including anxiolytic, sedative, and anticonvulsant activity. A solution of allopregnanolone, SAGE-547 is an intravenous allosteric modulator of both synaptic and extrasynaptic γ-aminobutyric acid type A (GABAA)receptors. It's believed that allopregnanolone is effective as an anticonvulsant when prolonged seizure activity has become resistant to benzodiazepine treatment. Under the names brexanolone and SAGE-547, allopregnanolone is under development by SAGE Therapeutics as an intravenously administered drug for the treatment of super-refractory status epilepticus, postpartum depression, and essential tremor. Allopregnanolone is in phase III trials for the treatment of super-refractory status epilepticus (SRSE) and postpartum depression.

Rifamycin SV is a derivative of antibiotic rifamycin B (the natural fermentation product of S. mediterranei broths). The primary target of rifampicin on whole bacteria is the synthesis of RNA. Rifamycin belongs to the ansamycin class of antibacterial drugs and acts by inhibiting the beta subunit of the bacterial DNA-dependent RNA polymerase, blocking one of the steps in DNA transcription. This results in inhibition of bacterial synthesis and consequently growth of bacteria. Rifampicin exhibits bactericidal activity on Gram-positive and Gram-negative bacteria and on mycobacteria. Rifamycin SV MMX® (AEMCOLO), a non-absorbable rifamycin antibiotic formulated using the multi-matrix system, was designed to exhibit its pharmacological action on the distal small intestine and colon. AEMCOLO is indicated for the treatment of travelers’ diarrhea (TD) caused by non-invasive strains of Escherichia coli in adults.
