Sirolimus, also known as rapamycin and sold under the brand name Rapamune among others, is a macrolide compound that is used to coat coronary stents, prevent organ transplant rejection, treat a rare lung disease called lymphangioleiomyomatosis, and treat perivascular epithelioid cell tumor (PEComa). It has immunosuppressant functions in humans and is especially useful in preventing the rejection of kidney transplants. It is a mechanistic target of rapamycin (mTOR) kinase inhibitor that reduces the sensitivity of T cells and B cells to interleukin-2 (IL-2), inhibiting their activity.

The mammalian target of rapamycin (mTOR), also referred to as the mechanistic target of rapamycin, and sometimes called FK506-binding protein 12-rapamycin-associated protein 1 (FRAP1), is a kinase that in humans is encoded by the MTOR gene. mTOR is a member of the phosphatidylinositol 3-kinase-related kinase family of protein kinases.

Ribosomal protein S6 kinase beta-1 (S6K1), also known as p70S6 kinase, is an enzyme that in humans is encoded by the RPS6KB1 gene. It is a serine/threonine kinase that acts downstream of PIP3 and phosphoinositide-dependent kinase-1 in the PI3 kinase pathway. As the name suggests, its target substrate is the S6 ribosomal protein.

<span class="mw-page-title-main">MLST8</span> Protein-coding gene in humans

Target of rapamycin complex subunit LST8, also known as mammalian lethal with SEC13 protein 8 (mLST8) or TORC subunit LST8 or G protein beta subunit-like, is a protein that in humans is encoded by the MLST8 gene. It is a subunit of both mTORC1 and mTORC2, complexes that regulate cell growth and survival in response to nutrient, energy, redox, and hormonal signals. It is upregulated in several human colon and prostate cancer cell lines and tissues. Knockdown of mLST8 prevented mTORC formation and inhibited tumor growth and invasiveness.

mTOR inhibitors Class of pharmaceutical drugs

mTOR inhibitors are a class of drugs that inhibit the mammalian target of rapamycin (mTOR), which is a serine/threonine-specific protein kinase that belongs to the family of phosphatidylinositol-3 kinase (PI3K) related kinases (PIKKs). mTOR regulates cellular metabolism, growth, and proliferation by forming and signaling through two protein complexes, mTORC1 and mTORC2. The most established mTOR inhibitors are so-called rapalogs, which have shown tumor responses in clinical trials against various tumor types.

mTORC1 Protein complex

mTORC1, also known as mammalian target of rapamycin complex 1 or mechanistic target of rapamycin complex 1, is a protein complex that functions as a nutrient/energy/redox sensor and controls protein synthesis.

mTOR Complex 2 (mTORC2) is an acutely rapamycin-insensitive protein complex formed by serine/threonine kinase mTOR that regulates cell proliferation and survival, cell migration and cytoskeletal remodeling. The complex itself is rather large, consisting of seven protein subunits. The catalytic mTOR subunit, DEP domain containing mTOR-interacting protein (DEPTOR), mammalian lethal with sec-13 protein 8, and TTI1/TEL2 complex are shared by both mTORC2 and mTORC1. Rapamycin-insensitive companion of mTOR (RICTOR), mammalian stress-activated protein kinase interacting protein 1 (mSIN1), and protein observed with rictor 1 and 2 (Protor1/2) can only be found in mTORC2. Rictor has been shown to be the scaffold protein for substrate binding to mTORC2.

Immunometabolism is a branch of biology that studies the interplay between metabolism and immunology in all organisms. In particular, immunometabolism is the study of the molecular and biochemical underpinninngs for i) the metabolic regulation of immune function, and ii) the regulation of metabolism by molecules and cells of the immune system. Further categorization includes i) systemic immunometabolism and ii) cellular immunometabolism. Immunometabolism includes metabolic inflammation:a chronic, systemic, low grade inflammation, orchestrated by metabolic deregulation caused by obesity or aging.

<span class="mw-page-title-main">HY-124798</span> Chemical compound

HY-124798 (Rheb inhibitor NR1) is the first compound to be developed that acts as a potent and selective inhibitor of Rheb, a GTP-binding protein which acts as an endogenous activator of the mechanistic target of rapamycin (mTOR) subtype mTORC1. Since many of the side effects of rapamycin and its analogues are thought to result from binding to the other subtype mTORC2, it is hoped that selective inhibition of mTORC1 should have a more selective effects profile. As mTORC1 and mTORC2 have binding sites that are very similar in structure, it has been challenging to develop highly subtype selective inhibitors, making indirect inhibition via modulation of other messenger proteins such as Rheb an attractive approach. However, since HY-124798 has a relatively weak IC50 of 2.1μM, and Rheb also has other targets in addition to mTORC1, it remains to be established whether it will deliver the hoped for improvements in pharmacological profile.
