LSG1 Inhibitors
LSG1 inhibitors encompass a range of chemical compounds that impair its function in the process of ribosome biogenesis and protein synthesis via various indirect mechanisms. One such compound is Rapamycin, which by inhibiting the mTORC1 complex, attenuates ribosomal protein synthesis and, therefore, the functional demand for LSG1 that is integral to this process. Cycloheximide and Anisomycin also disrupt protein synthesis by inhibiting the translocation step and peptidyl transferase activity, respectively, which lessens the need for LSG1's role in ribosome assembly. Similarly, Hydroxyurea, Actinomycin D, and Alpha-amanitin target DNA and RNA synthesis pathways, leading to a reduction in the cellular requirements for new ribosomes and consequently, LSG1 function. Tunicamycin's inhibition of N-linked glycosylation, though not directly related to LSG1, can hamper cellular homeostasis and indirectly affect LSG1's role in the assembly of ribosomes.
Additional inhibitors operate by disrupting processes that are essential for the full functionality of ribosomes, thereby indirectly diminishing the biological role of LSG1. Brefeldin A disrupts protein processing and transport within the Golgi apparatus, which could lead to less efficient ribosome assembly and a decreased need for LSG1 activity. Ricin, a potent ribosome-inactivating protein, incapacitates ribosomes by modifying rRNA, which in turn indirectly lessens the functional requirement for LSG1 in ribosome biogenesis. Puromycin, Emetine, and Harringtonine each inhibit different stages of protein synthesis at the ribosome, thereby reducing the need for LSG1's facilitation in this process. Through these varied modes of action, each chemical compound indirectly impacts the functional activity of LSG1, underscoring their collective role as indirect inhibitors of this protein.

Rapamycin | 53123-88-9 | sc-3504 sc-3504A sc-3504B | 1 mg 5 mg 25 mg | $63.00 $158.00 $326.00 | 233 | |
Rapamycin is an mTOR inhibitor that can suppress protein synthesis by inhibiting the mTORC1 complex, which is involved in ribosomal biogenesis and translation initiation. Inhibition of mTORC1 can indirectly diminish LSG1 function by reducing ribosomal protein synthesis. | ||||||
Cycloheximide | 66-81-9 | sc-3508B sc-3508 sc-3508A | 100 mg 1 g 5 g | $41.00 $84.00 $275.00 | 127 | |
Cycloheximide is a protein synthesis inhibitor that blocks the translocation step in protein elongation. By inhibiting protein synthesis globally, it can diminish the levels of LSG1 protein indirectly. | ||||||
Hydroxyurea | 127-07-1 | sc-29061 sc-29061A | 5 g 25 g | $78.00 $260.00 | 18 | |
Hydroxyurea inhibits ribonucleotide reductase, leading to decreased levels of deoxyribonucleotides and consequently DNA synthesis. This stalls the cell cycle, which may indirectly decrease the demand for LSG1's ribosome assembly function. | ||||||
Actinomycin D | 50-76-0 | sc-200906 sc-200906A sc-200906B sc-200906C sc-200906D | 5 mg 25 mg 100 mg 1 g 10 g | $74.00 $243.00 $731.00 $2572.00 $21848.00 | 53 | |
Actinomycin D binds to DNA and inhibits RNA synthesis. By preventing mRNA synthesis, it can indirectly lead to a reduction in LSG1 protein levels as there would be less mRNA available for translation. | ||||||
α-Amanitin | 23109-05-9 | sc-202440 sc-202440A | 1 mg 5 mg | $269.00 $1050.00 | 26 | |
Alpha-amanitin is a potent inhibitor of RNA polymerase II, which is responsible for mRNA synthesis. By blocking mRNA production, it can indirectly reduce LSG1 protein levels since the translation of new LSG1 protein would be impaired. | ||||||
Tunicamycin | 11089-65-9 | sc-3506A sc-3506 | 5 mg 10 mg | $172.00 $305.00 | 66 | |
Tunicamycin blocks N-linked glycosylation. Although LSG1 is not glycosylated, this inhibition can disrupt overall cellular homeostasis and potentially diminish LSG1 function in ribosome biogenesis by affecting the folding and stability of glycoproteins that interact with ribosomes. | ||||||
Anisomycin | 22862-76-6 | sc-3524 sc-3524A | 5 mg 50 mg | $99.00 $259.00 | 36 | |
Anisomycin is a protein synthesis inhibitor that acts by blocking peptidyl transferase activity on the ribosome. This can indirectly affect LSG1's role in ribosome assembly by halting protein synthesis at the ribosome level. | ||||||
Brefeldin A | 20350-15-6 | sc-200861C sc-200861 sc-200861A sc-200861B | 1 mg 5 mg 25 mg 100 mg | $31.00 $53.00 $124.00 $374.00 | 25 | |
Brefeldin A disrupts the Golgi apparatus and protein trafficking. While not directly affecting LSG1, it can indirectly decrease the efficiency of ribosome assembly and function by misregulating protein transport and processing. | ||||||
