Gusacitinib (ASN002) is an investigational drug which acts as a pan-Janus kinase inhibitor, binding with similar affinity at JAK1, JAK2, JAK3 and TYK2, and also inhibiting spleen tyrosine kinase (SYK). [1] It is taken orally and was developed for the treatment of eczema and dermatitis. [2] [3] [4]

Janus kinase (JAK) is a family of intracellular, non-receptor tyrosine kinases that transduce cytokine-mediated signals via the JAK-STAT pathway. They were initially named "just another kinase" 1 and 2, but were ultimately published as "Janus kinase". The name is taken from the two-faced Roman god of beginnings, endings and duality, Janus, because the JAKs possess two near-identical phosphate-transferring domains. One domain exhibits the kinase activity, while the other negatively regulates the kinase activity of the first.

<span class="mw-page-title-main">Dermatitis</span> Inflammatory disease of the skin

Dermatitis is inflammation of the skin, typically characterized by itchiness, redness and a rash. In cases of short duration, there may be small blisters, while in long-term cases the skin may become thickened. The area of skin involved can vary from small to covering the entire body. Dermatitis is often called eczema, and the difference between those terms is not standardized.

<span class="mw-page-title-main">Seborrhoeic dermatitis</span> Skin disease

Seborrhoeic dermatitis is a long-term skin disorder. Symptoms include flaky, scaly, greasy, and occasionally itchy and inflamed skin. Areas of the skin rich in oil-producing glands are often affected including the scalp, face, and chest. It can result in social or self-esteem problems. In babies, when the scalp is primarily involved, it is called cradle cap. Seborrhoeic dermatitis of the scalp may be described in lay terms as dandruff due to the dry, flaky character of the skin. However, as dandruff may refer to any dryness or scaling of the scalp, not all dandruff is seborrhoeic dermatitis. Seborrhoeic dermatitis is sometimes inaccurately referred to as seborrhoea.

Pimecrolimus is an immunosuppressant drug of the calcineurin inhibitor class used in the treatment of atopic dermatitis (eczema).

Antipruritics, abirritants, or anti-itch drugs, are medications that inhibit the itching often associated with sunburns, allergic reactions, eczema, psoriasis, chickenpox, fungal infections, insect bites and stings like those from mosquitoes, fleas, and mites, and contact dermatitis and urticaria caused by plants such as poison ivy or stinging nettle. It can also be caused by chronic kidney disease and related conditions.

Dyshidrosis is a type of dermatitis, characterized by itchy vesicles of 1–2 mm in size, on the palms of the hands, sides of fingers, or bottoms of the feet. Outbreaks usually conclude within three to four weeks, but often recur. Repeated attacks may result in fissures and skin thickening. The cause of the condition is not known.

Atopic dermatitis (AD), also known as atopic eczema, is a long-term type of inflammation of the skin (dermatitis). It results in itchy, red, swollen, and cracked skin. Clear fluid may come from the affected areas, which can thicken over time. AD may also simply be called eczema, a term that generally refers to a larger group of skin conditions.

<span class="mw-page-title-main">Hand eczema</span> Skin condition

Hand eczema presents on the palms and soles, and may sometimes be difficult or impossible to differentiate from atopic dermatitis, allergic contact dermatitis, and psoriasis, which also commonly involve the hands. Even a biopsy of all these conditions may not result in a definitive diagnosis, as all three conditions may demonstrate spongiosis and crusting on the hands.

A Janus kinase inhibitor, also known as JAK inhibitor or jakinib, is a type of immune modulating medication, which inhibits the activity of one or more of the Janus kinase family of enzymes, thereby interfering with the JAK-STAT signaling pathway in lymphocytes.

Zotiraciclib (TG02) is a potent oral spectrum selective kinase inhibitor for the treatment of cancer. It was discovered in Singapore by S*BIO Pte Ltd and falls under the category of small molecule macrocycles. It crosses the blood brain barrier and acts by depleting Myc through the inhibition of cyclin-dependent kinase 9 (CDK9). It is one of a number of CDK inhibitors under investigation; others targeting CDK9 for the treatment of acute myeloid leukemia include alvocidib and atuveciclib. Myc overexpression is a known factor in many cancers, with 80 percent of glioblastomas characterized by this property. Zotiraciclib has been granted orphan drug designation by the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA) for the treatment of gliomas.
