l 134

L 134 is a bioactive chemical.

L134, an effective PROTAC BRD4 degrader, exhibits a DC50 value of 7.36 nM. The degradation of BRD4 by L134 is mediated through the ubiquitin-proteasome system in a DCAF11-dependent manner.

Sulfamethoxypyridazine (CL 13494) is a sulfanilamide antibacterial agent.

LML134 (LML-134) is an inverse agonist of Histamine 3 receptor (H3R)(hH3R cAMP and hH3R bdg with Kis of 0.3 nM and 12 nM).

D-myo-Inositol-1,3,4,5-tetraphosphate (Ins(1,3,4,5)-P4) is formed by the phosphorylation of Ins(1,4,5)P3 by inositol 1,4,5-triphosphate 3-kinase. Ins(1,3,4,5)-P4 increases intracellular calcium levels by two distinct mechanisms: opening calcium channels on both the endoplasmic reticulum to release calcium from internal stores and on the plasma membrane to allow the influx of calcium from outside the cell.

The inositol phosphates (IPs) are a family of molecules produced by altering the phosphorylation status of each of the six carbons on the cyclic inositol structure. They act as second messengers, regulating a wide array of cellular functions. D-myo-inositol-1,3,4,6-tetraphosphate(Ins(1,3,4,6)-P4) largely acts an intermediate, serving as substrate for inositol-1,3,4,6-tetraphosphate 5-kinase to produce inositol-1,3,4,5,6-pentaphosphate, or inositol-1,3,4,6-tetraphosphate 2-kinase to give inositol-1,2,3,4,6-pentaphosphate. These inositol pentaphosphates can be further phosphorylated to produce inositol-1,2,3,4,5,6-hexakisphosphate, or phytic acid, which serves diverse roles in eukaryotic tissues. Ins(1,3,4,6)-P4 is a poor activator of the inositol 1,4,5-trisphospate receptor in vitro. Other functions of this IP remain to be elucidated.

Antifungalagent 134 (Compound B13) is an antifungal agent effective against Botrytis cinerea, Alternaria solani, Fusarium graminearum, Rhizoctonia solani, Colletotrichum orbiculare, and Alternaria alternata with EC50 values of 3.24, 1.89, 1.70, 0.36, 4.27, and 1.50 μg/mL, respectively. It disrupts the fungal cell membranes and mitochondria, leading to substantial accumulation of reactive oxygen species (ROS). Additionally, Antifungalagent 134 exhibits significant herbicidal activity on field weeds such as Amaranthus retroflexus L and Abutilon theophrasti Medicus, and is applicable in crop disease and field weed research.

Destruxin B2 is a cyclic hexadepsipeptide mycotoxin that has been found in M. anisopliae and has antiviral, insecticidal, and phytotoxic activities.1,2,3 It inhibits secretion of hepatitis B virus surface antigen (HBsAg) by Hep3B cells expressing hepatitis B virus (HBV) DNA (IC50 = 1.3 μM).1 Destruxin B2 is toxic to Sf9 insect cells in an electric cell-substrate impedance sensing (ECIS) test with a 50% inhibitory concentration (ECIS50) value of 92 μM.4 It is also phytotoxic to B. napus leaves.3 |1.
