FMX101 4% minocycline is a hydrophobic, topical foam formulation of minocycline recently approved by the United States Food and Drug Administration (FDA) for the treatment of non-nodular inflammatory lesions in moderate-to-severe acne vulgaris. It was developed to harness the anti-inflammatory and antibiotic activity of minocycline while minimizing potentially serious systemic adverse events associated with oral delivery. The composition and profile of this novel treatment have yet to be described.

FMX101 4% minocycline foam (FMX101 4%) is a novel, topical minocycline formulation for treatment of acne vulgaris. We report that FMX101 4% had an MIC of 0.25 μg/ml and was ≥4-fold more active than comparator antimicrobials against a panel of 98 clinical Cutibacterium acnes isolates.

This study sought to evaluate the long-term safety and efficacy of FMX101 4% topical minocycline foam for the treatment of moderate-to-severe acne. This was an open-label extension of two double-blind studies, Study 04 and Study 05. Subjects were enrolled at 35 sites in the United States and one site in the Dominican Republic.

FMX101 4% contains 4% micronized minocycline (as an HCl) formulated in a lipophilic foam vehicle for topical administration. FMX101 4% has been shown to be an effective and well-tolerated treatment for moderate-to-severe acne in three Phase 3 pivotal studies, however, skin sensitization and toxicity potential remains to be fully evaluated. Four single-center, randomized, controlled, within-subject comparison studies were conducted to evaluate the potential for phototoxicity, photoallergy, skin sensitization, and cumulative skin irritation with topical administration of FMX101 4% and the corresponding vehicle.

Ultrasound (US) imaging is a widely used clinical diagnostic tool in medical imaging techniques. It is a comparatively safe, economical, painless, portable, and noninvasive real-time tool compared to the other imaging modalities. However, the image quality of US imaging is severely affected by the presence of speckle noise and blur during the acquisition process.

Compared with other medical-imaging modalities, ultrasound (US) imaging is a valuable way to examine the body's internal organs, and two-dimensional (2D) imaging is currently the most common technique used in clinical diagnoses. Conventional 2D US imaging systems are highly flexible cost-effective imaging tools that permit operators to observe and record images of a large variety of thin anatomical sections in real time. Recently, 3D US imaging has also been gaining popularity due to its considerable advantages over 2D US imaging.

The main difficulty in the development of ATP antagonist kinase inhibitors is target specificity, since the ATP-binding motif is present in many proteins. We introduce a strategy that has allowed us to identify compounds from a kinase inhibitor library that block the cyclin-dependent kinases responsible for regulating transcription, i.e.

Through cell-based screening of our kinase-directed compound collection, we discovered that a subset of N-phenyl-4-(thiazol-5-yl)pyrimidin-2-amines were potent cytotoxic agents against cancer cell lines, suppressed mitotic histone H3 phosphorylation, and caused aberrant mitotic phenotypes. It was subsequently established that these compounds were in fact potent inhibitors of aurora A and B kinases. It was shown that potency and selectivity of aurora kinase inhibition correlated with the presence of a substituent at the aniline para-position in these compounds.

Seliciclib (R-roscovitine, CYC202) is a small molecule inhibitor of cyclin-dependent kinases currently in phase II clinical trials as an anticancer agent. We examined the metabolism of seliciclib in vitro and in vivo. Using radiolabeled seliciclib we found that cytochrome P450 (P450)-mediated metabolism in liver microsomes from human, rat, mouse, rabbit, monkey, and dog was rapid to a number of metabolic species, one of the most prevalent being a carboxylate previously identified in urine from rats and mice dosed with seliciclib.
