LEFAMULIN is a pleuromutilin antibiotic under development for the treatment of community-acquired bacterial pneumonia, as well as acute bacterial skin and skin structure infections. It inhibits bacterial protein synthesis by binding to the peptidyl transferase center of the 50S ribosome, resulting in the cessation of bacterial growth.

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.

Lofexidine is newly FDA approved in the United States under the brand name LUCEMYRA for the treatment of opioid withdrawal symptoms in adults. Lofexidine acts as an agonist to α2 adrenergic receptors. These receptors inhibit adenylyl cyclase activity, leading to the inhibition of the second messenger, cyclic adenosine monophosphate (cAMP). The inhibition of cAMP leads to potassium efflux through calcium-activated channels, blocking calcium ions from entering the nerve terminal, resulting in suppression of neural firing, inhibition of norepinephrine release. Lofexidine replaces the opioid-driven inhibition of cAMP production and moderating the symptoms of opioid withdrawal.

Midostaurin, a derivate of staurosporine (N-benzoylstaurosporine), is a broad-spectrum inhibitor of Ser/Thr and Tyr protein kinases. Midostaurin showed broad antiproliferative activity against various tumor and normal cell lines in vitro and is able to reverse the p-glycoprotein-mediated multidrug resistance of tumor cells in vitro. Midostaurin showed in vivo antitumor activity as single agent and inhibited angiogenesis in vivo. At the end of 2016 FDA granted Priority Review to the PKC412 (midostaurin) new drug application (NDA) for the treatment of acute myeloid leukemia (AML) in newly-diagnosed adults with an FMS-like tyrosine kinase-3 (FLT3) mutation, as well as for the treatment of advanced systemic mastocytosis (SM).

Lifitegrast (under brand name Xiidra) was approved as an ophthalmic solution for the treatment of the signs and symptoms of dry eye disease. Lifitegrast binds to the integrin lymphocyte function-associated antigen-1 (LFA-1); a cell surface protein found on leukocytes and blocks the interaction of LFA-1 with its cognate ligand intercellular adhesion molecule-1 (ICAM-1). This LFA-1/ICAM-1 interaction is a key step in the inflammatory cascade that contributes to dry eye disease. Besides lifitegrast participates in phase II clinical trials for prevention of the signs and symptoms of allergic conjunctivitis.

Abiraterone acetate (trade name Zytiga) is a prodrug to the abiraterone, steroidal compound with antiandrogen activity and a 17 α-hydroxylase/C17,20-lyase (CYP17) inhibitor. It is indicated in combination with prednisone for the treatment of patients with metastatic castration-resistant prostate cancer. Abiraterone acetate is converted in vivo to abiraterone which inhibits CYP17, enzyme expressed in testicular, adrenal, and prostatic tumor tissues and required for androgen biosynthesis. Administration of this agent may suppress testosterone production by both the testes and the adrenals to castrate-range levels. Androgen sensitive prostatic carcinoma responds to treatment that decreases androgen levels. Androgen deprivation therapies, such as treatment with GnRH agonists or orchiectomy, decrease androgen production in the testes but do not affect androgen production by the adrenals or in the tumor.

Rotigotine is an agonist at all 5 dopamine receptor subtypes (D1-D5) but binds to the D3 receptor with the highest affinity. It is also an antagonist at α-2-adrenergic receptors and an agonist at the 5HT1A receptors. Rotigotine also inhibits dopamine uptake and prolactin secretion. It is FDA approved for the treatment of Parkinson's disease, restless legs syndrome. Dopamine antagonists, such as antipsychotics or metoclopramide, may diminish the effectiveness of Rotigotine. Common adverse reactions include nausea, vomiting, somnolence, application site reactions, dizziness, anorexia, hyperhidrosis, insomnia and dyskinesia.

Sunitinib (marketed as Sutent by Pfizer, and previously known as SU11248) is an oral, small-molecule, multi-targeted receptor tyrosine kinase inhibitor that was approved by the FDA for the treatment of renal cell carcinoma (RCC) and imatinib-resistant gastrointestinal stromal tumor. Sunitinib was evaluated for its inhibitory activity against a variety of kinases and was identified as an inhibitor of platelet-derived growth factor receptors (PDGFRa and PDGFRb), vascular endothelial growth factor receptors (VEGFR1, VEGFR2, and VEGFR3), stem cell factor receptor (KIT), Fms-like tyrosine kinase-3 (FLT3), colony-stimulating factor receptor Type 1 (CSF-1R), and the glial cell-line derived neurotrophic factor receptor (RET). Sunitinib adverse events are considered somewhat manageable and the incidence of serious adverse events low. The most common adverse events associated with sunitinib therapy are fatigue, diarrhea, nausea, anorexia, hypertension, yellow skin discoloration, hand-foot skin reaction, and stomatitis. In the placebo-controlled Phase III GIST study, adverse events which occurred more often with sunitinib than placebo included diarrhea, anorexia, skin discoloration, mucositis/stomatitis, asthenia, altered taste, and constipation. Dose reductions were required in 50% of the patients studied in RCC in order to manage the significant toxicities of this agent.

Alfuzosin is a quinazoline-derivative alpha-adrenergic blocking agent used to treat hypertension and benign prostatic hyperplasia. Alfuzosin is marketed in the United States by Sanofi Aventis under the brand name Uroxatral. UROXATRAL (alfuzosin HCl extended-release tablets) is indicated for the treatment of the signs and symptoms of benign prostatic hyperplasia. UROXATRAL is not indicated for the treatment of hypertension. Alfuzosin is a non-subtype specific alpha(1)-adrenergic blocking agent that exhibits selectivity for alpha(1)-adrenergic receptors in the lower urinary tract. Inhibition of these adrenoreceptors leads to the relaxation of smooth muscle in the bladder neck and prostate, resulting in the improvement in urine flow and a reduction in symptoms in benign prostate hyperplasia. Alfuzosin also inhibits the vasoconstrictor effect of circulating and locally released catecholamines (epinephrine and norepinephrine), resulting in peripheral vasodilation.
